CATO supplies 2-((4-Allyl-5-oxo-4,5-dihydro-[1,2,4]triazolo[4,3-a]quinazolin-1-yl)thio)acetic acid (CAS 742094-79-7), a certified reference material (molecular formula C14H12N4O3S, MW 316.34 g/mol) for analytical method development and quality control.
The molecular framework of 2-((4-Allyl-5-oxo-4,5-dihydro-[1,2,4]triazolo[4,3-a]quinazolin-1-yl)thio)acetic acid (C14H12N4O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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-((4-Allyl-5-oxo-4,5-dihydro-[1,2,4]triazolo[4,3-a]quinazolin-1-yl)thio)acetic 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.
