Chemical Structure

3,5-Dimethyl-1-phenyl-1H-pyrazole-4-carboxylic acid ethyl ester CAS 89193-18-0 chemical structure

Description

CATO manufactures 3,5-Dimethyl-1-phenyl-1H-pyrazole-4-carboxylic acid ethyl ester 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.

3,5-Dimethyl-1-phenyl-1H-pyrazole-4-carboxylic acid ethyl ester (CAS 89193-18-0), molecular formula C14H16N2O2 and molecular weight 244.29 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 3,5-Dimethyl-1-phenyl-1H-pyrazole-4-carboxylic acid ethyl ester is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 244.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.
