Methyl 4-cyano-1H-pyrazole-3-carboxylate CAS 105020-45-9

Description

The occurrence of Methyl 4-cyano-1H-pyrazole-3-carboxylate is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Methyl 4-cyano-1H-pyrazole-3-carboxylate (CAS 105020-45-9), a certified reference material (molecular formula C6H5N3O2, MW 151.12 g/mol) for analytical method development and quality control.

The molecular framework of Methyl 4-cyano-1H-pyrazole-3-carboxylate (C6H5N3O2) 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 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.

As a certified reference material (CRM), Methyl 4-cyano-1H-pyrazole-3-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
