Product Description
(4-Boc-Aminophenyl)boronic acid is a biochemical compound that could be utilized as a biomaterial or organic/chemical reagent for biomedical research.
(4-Boc-aminophenyl)boronic acid (CAS 380430-49-9) is a functionalized arylboronic acid derivative combining a boronic acid moiety with a Boc-protected para-amino group. Its molecular formula is C11H16BNO4 and its molecular weight is 237.06 g/mol. This compound is a biochemical reagent used as a biomaterial for life science research and as a sulfonylation reagent for organic synthesis and drug discovery. It serves as a substrate in CuO-catalyzed three-component reactions with α-ketoaldehydes and 1,3-dicarbonyl compounds in water to produce 1,4-diketone products. The Boc protecting group allows for selective deprotection under acidic conditions, enabling further functionalization.
Biological Activity I Assay Protocols (From Reference)
Targets
(4-Boc-aminophenyl)boronic acid does not have a specific biological target. It is a chemical reagent and building block used in organic synthesis and drug discovery. The boronic acid moiety can reversibly bind to diols and is used in the synthesis of boron-containing drugs such as proteasome inhibitors (e.g., bortezomib). The compound itself is not pharmacologically active but serves as a precursor for synthesizing bioactive molecules.
ln Vitro
(4-Boc-aminophenyl)boronic acid is a chemical reagent and does not possess intrinsic in vitro biological activity. Its value lies in its utility for synthesizing biologically active molecules, particularly boron-containing drugs and other pharmaceutical intermediates. The compound is used in Suzuki-Miyaura cross-coupling reactions to construct biaryl structures found in many drug molecules. It is also used in the synthesis of 1,4-diketone products in water.
ln Vivo
This compound is not a pharmacologically active agent and does not have intrinsic in vivo activity. Its applications in vivo are limited to its use as a synthetic intermediate for producing drug candidates that are subsequently evaluated in animal models. The compound is not administered to animals as a test compound.
Enzyme Assay
(4-Boc-aminophenyl)boronic acid is not typically used in cell-free enzyme/receptor binding assays. Its role in drug discovery is as a synthetic building block. For compounds synthesized using this reagent, typical binding assays may be performed. These involve incubating the test compound with purified enzymes or receptors in buffered solutions (e.g., PBS or Tris-HCl, pH 7.4) at 25–37°C, with binding affinity measured by SPR, ITC, or fluorescence-based methods.
Cell Assay
Cell-based assays are not directly performed on (4-Boc-aminophenyl)boronic acid due to its lack of biological activity. However, drug candidates synthesized from this intermediate may be tested in cellular systems. Typical studies involve culturing cells (e.g., cancer cell lines) in appropriate media, treating with the synthesized compound, and assessing cell viability (MTT), apoptosis, and other endpoints over 24–72 hours. The compound's boronic acid moiety may be used to synthesize proteasome inhibitors for cellular testing.
Animal Protocol
In vivo animal studies are not conducted with (4-Boc-aminophenyl)boronic acid itself, as it is a chemical reagent. Drug candidates synthesized from this intermediate may be evaluated in animal models for efficacy, pharmacokinetics, and toxicity. Typical studies involve oral or intravenous administration to rodents, with monitoring of plasma drug levels, tissue distribution, and disease-relevant endpoints. All studies follow institutional animal care guidelines.
ADME/Pharmacokinetics
(4-Boc-aminophenyl)boronic acid is a synthetic chemical reagent and is not subject to pharmacokinetic evaluation as a drug. Its physicochemical properties include a molecular weight of 237.06 g/mol and a molecular formula of C11H16BNO4. The compound is stable under normal storage conditions and is available in high purity (≥98%). The Boc protecting group provides stability and allows selective deprotection under acidic conditions.
Toxicity/Toxicokinetics
The toxicological profile of (4-Boc-aminophenyl)boronic acid has not been extensively characterized. As a boronic acid derivative, it may pose health hazards, including skin and eye irritation. Standard laboratory safety precautions should be observed, including the use of personal protective equipment (gloves, goggles, lab coat) and adequate ventilation. Ingestion or inhalation should be avoided. Appropriate first-aid measures should be in place.
Additional Infomation
(4-Boc-aminophenyl)boronic acid is not a drug but a valuable chemical reagent and building block for organic synthesis and drug discovery. It is an arylboronic acid derivative that can be used in Suzuki-Miyaura cross-coupling reactions to construct complex biaryl structures. The Boc-protected amino group enables selective deprotection for further functionalization. It is used as a biochemical reagent for life science research and as a sulfonylation reagent. It is not approved for clinical use.

Solubility Data
Solubility (In Vitro)
DMSO: 100 mg/mL (421.83 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.5 mg/mL (10.55 mM) (saturation unknown) in 10% DMSO + 40% PEG300 +5% Tween-80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 + to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

 (Please use freshly prepared in vivo formulations for optimal results.)
Preparing Stock Solutions 1 mg 5 mg 10 mg
1 mM 4.2183 mL 21.0917 mL 42.1834 mL
5 mM 0.8437 mL 4.2183 mL 8.4367 mL
10 mM 0.4218 mL 2.1092 mL 4.2183 mL

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
