Chemical Structure

1-Methyl-5-phenoxy-3-(trifluoromethyl)-1H-pyrazole-4-carbonitrile CAS 916766-95-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Methyl-5-phenoxy-3-(trifluoromethyl)-1H-pyrazole-4-carbonitrile.

1-Methyl-5-phenoxy-3-(trifluoromethyl)-1H-pyrazole-4-carbonitrile (CAS 916766-95-5) is a high-purity analytical reference standard with the molecular formula C12H8F3N3O and a molecular weight of 267.21 g/mol.

The molecular framework of 1-Methyl-5-phenoxy-3-(trifluoromethyl)-1H-pyrazole-4-carbonitrile (C12H8F3N3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

CATO manufactures 1-Methyl-5-phenoxy-3-(trifluoromethyl)-1H-pyrazole-4-carbonitrile 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.
