Ethyl 5-cyano-4-methyl-1H-pyrazole-3-carboxylate CAS 829-06-1

Description

Compared with other compounds in its class, the molecular weight of 179.18 g/mol gives Ethyl 5-cyano-4-methyl-1H-pyrazole-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyl 5-cyano-4-methyl-1H-pyrazole-3-carboxylate (CAS 829-06-1), molecular formula C8H9N3O2 and molecular weight 179.18 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Ethyl 5-cyano-4-methyl-1H-pyrazole-3-carboxylate (C8H9N3O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 Ethyl 5-cyano-4-methyl-1H-pyrazole-3-carboxylate 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.
