2-((6,7-Dimethoxy-3-methyl-4-oxo-3,4-dihydroquinazolin-2-yl)thio)acetic acid CAS 886500-86-3

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-((6,7-Dimethoxy-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 310.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

2-((6,7-Dimethoxy-3-methyl-4-oxo-3,4-dihydroquinazolin-2-yl)thio)acetic acid (CAS 886500-86-3) is a high-purity analytical reference standard with the molecular formula C13H14N2O5S and a molecular weight of 310.33 g/mol.

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.

As a certified reference material (CRM), 2-((6,7-Dimethoxy-3-methyl-4-oxo-3,4-dihydroquinazolin-2-yl)thio)acetic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
