The occurrence of 3-{[(2-methylphenyl)sulfanyl]methyl}-2H,3H,5H-[1,3]thiazolo[2,3-b]quinazolin-5-one is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-{[(2-methylphenyl)sulfanyl]methyl}-2H,3H,5H-[1,3]thiazolo[2,3-b]quinazolin-5-one (CAS 477860-16-5), molecular formula C18H16N2OS2 and molecular weight 340.46 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-{[(2-methylphenyl)sulfanyl]methyl}-2H,3H,5H-[1,3]thiazolo[2,3-b]quinazolin-5-one (C18H16N2OS2) 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 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 3-{[(2-methylphenyl)sulfanyl]methyl}-2H,3H,5H-[1,3]thiazolo[2,3-b]quinazolin-5-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.
