7-Chloro-N-[(3,4-dimethoxyphenyl)methyl]quinazolin-4-amine CAS 477861-86-2

Description

The occurrence of 7-Chloro-N-[(3,4-dimethoxyphenyl)methyl]quinazolin-4-amine is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

7-Chloro-N-[(3,4-dimethoxyphenyl)methyl]quinazolin-4-amine (CAS 477861-86-2), molecular formula C17H16ClN3O2 and molecular weight 329.78 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 7-Chloro-N-[(3,4-dimethoxyphenyl)methyl]quinazolin-4-amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 329.78 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
