Product Description
Isoquinolin-1-amine (1-Aminoisoquinoline) is a substance that can be used to synthesize pyrimidinyl isoquinolinones.
Isoquinolin-1-amine (1532-84-9), also known as 1-aminoisoquinoline, is a nitrogen-containing heterocyclic compound featuring an isoquinoline core with an amino group at the 1-position. This aromatic amine serves as a versatile synthetic intermediate in organic and medicinal chemistry. It is utilized for the synthesis of more complex pharmaceutical compounds, including pyrimidinylisoquinolinone derivatives. The compound exhibits significant stability and appears as a solid with a melting point of 119-123degC. Its molecular formula is C9H8N2 with a molecular weight of approximately 144.17 g/mol, and purity typically exceeds 98.0% by GC.
Biological Activity I Assay Protocols (From Reference)
Targets
Isoquinolin-1-amine (1532-84-9) does not have a defined pharmacological target as it is primarily a synthetic building block and biochemical assay reagent rather than a therapeutic agent. The compound is functionally related to isoquinoline derivatives, many of which exhibit diverse biological activities including kinase inhibition, antimicrobial, and anticancer properties. However, the parent compound itself is not known to bind to any specific protein or receptor. Its primary role is as a chemical intermediate for the synthesis of bioactive molecules with defined targets.
ln Vitro
Not applicable for Isoquinolin-1-amine (1532-84-9) as it is a synthetic intermediate without documented direct biological activity. The compound is classified as a biochemical assay reagent and building block for pharmaceutical synthesis. No IC50, EC50, or other potency values have been reported for this substance in the context of target-based assays. For its downstream derivatives synthesized from this intermediate, biological activities may vary widely depending on the final molecular scaffold and functional groups introduced.
ln Vivo
Not applicable for Isoquinolin-1-amine (1532-84-9) as it is a synthetic intermediate without documented in vivo biological activity. The compound is intended for chemical synthesis rather than pharmacological evaluation in animal models. It does not possess intrinsic therapeutic properties as a standalone agent. Any in vivo activity would be associated with the final drug compounds that incorporate this isoquinoline fragment, not with the intermediate itself. The compound is not typically administered to animals for efficacy studies.
Enzyme Assay
Not applicable for Isoquinolin-1-amine (1532-84-9) as it is a synthetic intermediate without reported receptor binding assays. For general organic chemistry applications, no protein or receptor binding assays have been reported. Standard analytical characterization for this compound includes NMR spectroscopy, GC analysis, and mass spectrometry for structural confirmation and purity determination (typically >98% by GC). These methods are used for quality control but are not biological binding assays.
Cell Assay
Not applicable for Isoquinolin-1-amine (1532-84-9) as it is a synthetic intermediate without cell-based activity. This compound is not typically used in cell culture experiments as a pharmacologically active agent. Its primary applications are in organic synthesis as a starting material for drug manufacturing. However, as a biochemical reagent, it may be used in proteomics research for chemical labeling or as a precursor for synthesizing more complex molecules that are subsequently tested in cell-based assays.
Animal Protocol
Not applicable for Isoquinolin-1-amine (1532-84-9) as it is a synthetic intermediate without documented in vivo animal study protocols. The compound is used as a chemical precursor rather than as a test article for animal efficacy studies. Any animal studies involving this compound would be for toxicological safety assessment of the chemical itself, not for therapeutic efficacy evaluation. Standard OECD guidelines for chemical safety testing could apply, but no specific protocols are reported in the available literature for this compound.
ADME/Pharmacokinetics
Not applicable for Isoquinolin-1-amine (1532-84-9) as it is a synthetic intermediate without reported pharmacokinetic studies. The compound is not intended for systemic drug delivery. For chemical safety evaluation, the compound has predicted physicochemical properties including moderate water solubility, but no formal PK data in humans or animals have been reported. The substance is used primarily in research settings for synthetic chemistry and proteomics applications, not as a pharmaceutical candidate requiring PK characterization.
Toxicity/Toxicokinetics
Acute toxicity data for Isoquinolin-1-amine (1532-84-9) are not widely reported in the available literature. The compound is classified as an intermediate and reagent requiring standard laboratory safety precautions. It may cause skin and eye irritation upon direct contact. Inhalation of dust or vapors should be avoided. The compound should be handled in a well-ventilated area with appropriate personal protective equipment (gloves, lab coat, safety goggles). Storage conditions include protection from light and inert atmosphere. Potential chronic toxicity has not been evaluated.

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)
