Chemical Structure

4-Ethynyl-3,5-dimethyl-1-phenyl-1H-pyrazole CAS 51294-74-7 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

4-Ethynyl-3,5-dimethyl-1-phenyl-1H-pyrazole (CAS 51294-74-7) is a high-purity analytical reference standard with the molecular formula C13H12N2 and a molecular weight of 196.25 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 4-Ethynyl-3,5-dimethyl-1-phenyl-1H-pyrazole is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 196.25 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).

CATO manufactures 4-Ethynyl-3,5-dimethyl-1-phenyl-1H-pyrazole 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.
