Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-(1-Methyl-3-phenyl-5-(phenylthio)-1H-pyrazol-4-yl)-3-phenylprop-2-yn-1-ol (CAS 318959-35-2) is a high-purity analytical reference standard with the molecular formula C25H20N2OS and a molecular weight of 396.50 g/mol.
The molecular framework of 1-(1-Methyl-3-phenyl-5-(phenylthio)-1H-pyrazol-4-yl)-3-phenylprop-2-yn-1-ol (C25H20N2OS) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 1-(1-Methyl-3-phenyl-5-(phenylthio)-1H-pyrazol-4-yl)-3-phenylprop-2-yn-1-ol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
