Chemical Structure

3-Cycloheptyl-6,7-dimethoxy-2-[(2-methylpropyl)sulfanyl]-3,4-dihydroquinazolin-4-imine CAS 860786-40-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Cycloheptyl-6,7-dimethoxy-2-[(2-methylpropyl)sulfanyl]-3,4-dihydroquinazolin-4-imine.

CATO supplies 3-Cycloheptyl-6,7-dimethoxy-2-[(2-methylpropyl)sulfanyl]-3,4-dihydroquinazolin-4-imine (CAS 860786-40-9), a certified reference material (molecular formula C21H31N3O2S, MW 389.55 g/mol) for analytical method development and quality control.

Structurally, 3-Cycloheptyl-6,7-dimethoxy-2-[(2-methylpropyl)sulfanyl]-3,4-dihydroquinazolin-4-imine (C21H31N3O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 389.55 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
