Chemical Structure

(5-Chloro-1-methyl-3-((p-tolylthio)methyl)-1H-pyrazol-4-yl)methanol CAS 318234-43-4 chemical structure

Description

As a certified reference material (CRM), (5-Chloro-1-methyl-3-((p-tolylthio)methyl)-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-Chloro-1-methyl-3-((p-tolylthio)methyl)-1H-pyrazol-4-yl)methanol (CAS 318234-43-4) is a high-purity analytical reference standard with the molecular formula C13H15ClN2OS and a molecular weight of 282.79 g/mol.

The molecular framework of (5-Chloro-1-methyl-3-((p-tolylthio)methyl)-1H-pyrazol-4-yl)methanol (C13H15ClN2OS) is characterized by a nitrogen-containing heterocyclic scaffold, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
