Chemical Structure

2-amino-7-bromo-1,4-dihydroquinazolin-4-one CAS 885277-56-5 chemical structure

Description

The occurrence of 2-amino-7-bromo-1,4-dihydroquinazolin-4-one is closely related to an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-amino-7-bromo-1,4-dihydroquinazolin-4-one (CAS 885277-56-5) is a high-purity analytical reference standard with the molecular formula C8H14BrN3O and a molecular weight of 248.12 g/mol.

Structurally, 2-amino-7-bromo-1,4-dihydroquinazolin-4-one (C8H14BrN3O) contains an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 248.12 g/mol, it falls into the medium-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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
