4-chloro-8-isopropyl-2-methylsulfanyl-pyrazolo[1,5-a][1,3,5]triazine (CAS 1453186-96-3), molecular formula C9H19ClN4S and molecular weight 250.79 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-chloro-8-isopropyl-2-methylsulfanyl-pyrazolo[1,5-a][1,3,5]triazine (C9H19ClN4S) is characterized by a nitrile group, sulfur-containing functionality, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
