(1-Methyl-3-phenyl-5-(p-tolylthio)-1H-pyrazol-4-yl)methanol CAS 318233-99-7

Description

The occurrence of (1-Methyl-3-phenyl-5-(p-tolylthio)-1H-pyrazol-4-yl)methanol is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(1-Methyl-3-phenyl-5-(p-tolylthio)-1H-pyrazol-4-yl)methanol (CAS 318233-99-7) is a high-purity analytical reference standard with the molecular formula C18H18N2OS and a molecular weight of 310.41 g/mol.

The molecular framework of (1-Methyl-3-phenyl-5-(p-tolylthio)-1H-pyrazol-4-yl)methanol (C18H18N2OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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.

As a certified reference material (CRM), (1-Methyl-3-phenyl-5-(p-tolylthio)-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.
