1-Phenyl-4-(o-tolyl)-1H-pyrazole-5-carboxamide CAS 324009-00-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Phenyl-4-(o-tolyl)-1H-pyrazole-5-carboxamide.

1-Phenyl-4-(o-tolyl)-1H-pyrazole-5-carboxamide (CAS 324009-00-9) is a high-purity analytical reference standard with the molecular formula C16H15N3 and a molecular weight of 249.31 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 1-Phenyl-4-(o-tolyl)-1H-pyrazole-5-carboxamide is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 249.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures 1-Phenyl-4-(o-tolyl)-1H-pyrazole-5-carboxamide 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.
