Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-{[(2,6-dichlorophenyl)methyl]sulfanyl}-7-(4-methoxyphenyl)-[1,2,4]triazolo[1,5-a]pyrimidine.
2-{[(2,6-dichlorophenyl)methyl]sulfanyl}-7-(4-methoxyphenyl)-[1,2,4]triazolo[1,5-a]pyrimidine (CAS 338403-83-1), molecular formula C19H14Cl2N4OS and molecular weight 417.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-{[(2,6-dichlorophenyl)methyl]sulfanyl}-7-(4-methoxyphenyl)-[1,2,4]triazolo[1,5-a]pyrimidine (C19H14Cl2N4OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
