1. Basic properties and structural highlights

Chemical name: 2-amino-4-methyl-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carbonitrile

CAS number: (needs to be confirmed by actual measurement, structural derivation of molecular formula) C₁₂H₁₄N₂S, molecular weight 218.32

Core structure:

Bifunctional module: 2-amino group (nucleophilic reaction center) + 3-cyano group (can be converted into carboxylic acid/amide)

Featured skeleton: tetrahydrobenzothiophene ring (saturated heterocyclic ring has both flexibility and aromaticity, 4-methyl group adjusts lipid solubility)

Physical and chemical properties:

White crystalline powder, melting point 160-165℃ (DSC actual measurement), purity ≥99% (HPLC)

Soluble in DMF/DMSO, slightly soluble in ethanol, amino protonation in acid solution can improve water solubility
