Product Description
Propan-2-amine-d6 (HCl) is the deuterium labelled form of H-Lys-OH.2HCl.
Propan-2-amine-d6 HCl (Isopropylamine-d6 hydrochloride) is a stable isotope-labeled compound. It is the deuterium-labeled version of Propan-2-amine HCl. It is primarily used as an analytical internal standard for the quantification of isopropylamine and related compounds in various biological and environmental samples by mass spectrometry.
Biological Activity I Assay Protocols (From Reference)
Targets
Propan-2-amine-d6 HCl does not target a specific protein in drug research. It serves as an analytical internal standard and tracer. The deuterium labels (six hydrogen atoms replaced with deuterium) provide a mass shift, allowing precise differentiation from unlabeled isopropylamine in LC-MS or GC-MS analysis.
ln Vitro
Drug compounds have included stable heavy isotopes of carbon, hydrogen, and other elements, mostly as quantitative tracers while the drugs were being developed. Because deuteration may affect a drug's pharmacokinetics and metabolic properties, it is a cause for concern [75].
Propan-2-amine-d6 HCl is not typically used in bioactivity assays. Its unlabeled counterpart, isopropylamine, is a simple aliphatic amine used in various chemical syntheses. As an analytical standard, the labeled compound is used to quantify isopropylamine levels in metabolic or environmental studies.
ln Vivo
Dedicated in vivo activity studies are not performed for this stable isotope-labeled compound. It is used as an internal standard in PK studies to quantify the concentration of unlabeled isopropylamine or related drugs that are metabolized to isopropylamine in biological samples.
Enzyme Assay
Propan-2-amine-d6 HCl is used as an analytical internal standard. In a typical assay, a known amount of the labeled compound is spiked into a biological sample (e.g., plasma, urine, tissue homogenate). The sample is then extracted and analyzed by LC-MS/MS. The deuterated compound serves as an internal standard for quantification of the unlabeled analyte.
Cell Assay
Propan-2-amine-d6 HCl is not typically used in cell-based assays. Its primary application is in analytical chemistry rather than biological activity testing. It may be used to validate analytical methods for measuring isopropylamine in cell culture media or cell lysates.
Animal Protocol
In animal PK studies, Propan-2-amine-d6 HCl is used as an internal standard. The unlabeled isopropylamine is administered to animals, and the labeled compound is added to the collected plasma or tissue samples before extraction and LC-MS/MS analysis to accurately quantify the unlabeled isopropylamine concentration.
ADME/Pharmacokinetics
As an internal standard, Propan-2-amine-d6 HCl is not administered to animals for PK assessment of itself. Its PK properties are expected to be identical to unlabeled isopropylamine. Isopropylamine is rapidly absorbed and metabolized, with a short half-life. Detailed PK parameters are not typically reported.
Toxicity/Toxicokinetics
Propan-2-amine-d6 HCl is a stable isotope-labeled compound. At the trace levels used as an internal standard, it poses no toxicity risk. Unlabeled isopropylamine can be toxic at high doses, causing skin, eye, and respiratory irritation. Standard laboratory safety precautions for chemical handling apply.

*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.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • 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)
