2-(Methylthio)Pyrazolo[1,5-A][1,3,5]Triazin-4(3H)-One CAS 54346-18-8

Description

The occurrence of 2-(Methylthio)Pyrazolo[1,5-A][1,3,5]Triazin-4(3H)-One is closely related to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(Methylthio)Pyrazolo[1,5-A][1,3,5]Triazin-4(3H)-One (CAS 54346-18-8), molecular formula C6H6N4OS and molecular weight 182.20 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(Methylthio)Pyrazolo[1,5-A][1,3,5]Triazin-4(3H)-One (C6H6N4OS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. 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.

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.
