2-mercapto-3-(3-methoxypropyl)-4-oxo-3,4-dihydroquinazoline-7-carboxylic acid CAS 871478-73-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-mercapto-3-(3-methoxypropyl)-4-oxo-3,4-dihydroquinazoline-7-carboxylic acid.

CATO supplies 2-mercapto-3-(3-methoxypropyl)-4-oxo-3,4-dihydroquinazoline-7-carboxylic acid (CAS 871478-73-8), a certified reference material (molecular formula C13H14N2O4S, MW 294.33 g/mol) for analytical method development and quality control.

2-mercapto-3-(3-methoxypropyl)-4-oxo-3,4-dihydroquinazoline-7-carboxylic acid (C13H14N2O4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

CATO manufactures 2-mercapto-3-(3-methoxypropyl)-4-oxo-3,4-dihydroquinazoline-7-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
