Description

Compared with other compounds in its class, the molecular weight of 249.70 g/mol gives 5-Chloro-N,1-dimethyl-3-phenyl-1H-pyrazole-4-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Chloro-N,1-dimethyl-3-phenyl-1H-pyrazole-4-carboxamide (CAS 318237-81-9) is a high-purity analytical reference standard with the molecular formula C12H12ClN3O and a molecular weight of 249.70 g/mol.

Structurally, 5-Chloro-N,1-dimethyl-3-phenyl-1H-pyrazole-4-carboxamide (C12H12ClN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 249.70 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 5-Chloro-N,1-dimethyl-3-phenyl-1H-pyrazole-4-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.
