Description

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 supplies Methyl 5-oxo-1-thioxo-4,5-dihydro-1H-thiazolo[3,4-a]quinazoline-3-carboxylate (CAS 443107-42-4), a certified reference material (molecular formula C12H8N2O3S2, MW 292.33 g/mol) for analytical method development and quality control.

Methyl 5-oxo-1-thioxo-4,5-dihydro-1H-thiazolo[3,4-a]quinazoline-3-carboxylate (C12H8N2O3S2) 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).

CATO manufactures Methyl 5-oxo-1-thioxo-4,5-dihydro-1H-thiazolo[3,4-a]quinazoline-3-carboxylate 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.
