Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2-Methyl-5,7-diphenyl-2H-thiazolo[3,2-a]pyrimidin-3(5H)-one (CAS 138429-09-1), a certified reference material (molecular formula C19H16N2OS, MW 320.41 g/mol) for analytical method development and quality control.
The molecular framework of 2-Methyl-5,7-diphenyl-2H-thiazolo[3,2-a]pyrimidin-3(5H)-one (C19H16N2OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures 2-Methyl-5,7-diphenyl-2H-thiazolo[3,2-a]pyrimidin-3(5H)-one 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.
