Chemical Structure

N-(2-chlorophenyl)-1H-pyrazole-3-carboxamide CAS 305346-16-1 chemical structure

Description

The occurrence of N-(2-chlorophenyl)-1H-pyrazole-3-carboxamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies N-(2-chlorophenyl)-1H-pyrazole-3-carboxamide (CAS 305346-16-1), a certified reference material (molecular formula C10H8ClN3O, MW 221.64 g/mol) for analytical method development and quality control.

N-(2-chlorophenyl)-1H-pyrazole-3-carboxamide (C10H8ClN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), N-(2-chlorophenyl)-1H-pyrazole-3-carboxamide 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.
