Chemical Structure

2-((6,8-Dibromo-3-methyl-4-oxo-3,4-dihydroquinazolin-2-yl)thio)acetic acid CAS 886501-04-8 chemical structure

Description

The occurrence of 2-((6,8-Dibromo-3-methyl-4-oxo-3,4-dihydroquinazolin-2-yl)thio)acetic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-((6,8-Dibromo-3-methyl-4-oxo-3,4-dihydroquinazolin-2-yl)thio)acetic acid (CAS 886501-04-8) is a high-purity analytical reference standard with the molecular formula C11H8Br2N2O3S and a molecular weight of 408.07 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution, 2-((6,8-Dibromo-3-methyl-4-oxo-3,4-dihydroquinazolin-2-yl)thio)acetic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 408.07 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
