(5-((4-Chlorobenzyl)thio)-1-methyl-3-phenyl-1H-pyrazol-4-yl)methanol CAS 318959-22-7

Description

As a certified reference material (CRM), (5-((4-Chlorobenzyl)thio)-1-methyl-3-phenyl-1H-pyrazol-4-yl)methanol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

(5-((4-Chlorobenzyl)thio)-1-methyl-3-phenyl-1H-pyrazol-4-yl)methanol (CAS 318959-22-7), molecular formula C18H17ClN2OS and molecular weight 344.86 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (5-((4-Chlorobenzyl)thio)-1-methyl-3-phenyl-1H-pyrazol-4-yl)methanol (C18H17ClN2OS) 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 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.
