Chemical Structure
Description
The occurrence of 4-Chloro-1-(4-methylphenyl)-N-propyl-1H-pyrazole-5-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 4-Chloro-1-(4-methylphenyl)-N-propyl-1H-pyrazole-5-carboxamide (CAS 321571-53-3), a certified reference material (molecular formula C14H16ClN3O, MW 277.75 g/mol) for analytical method development and quality control.
4-Chloro-1-(4-methylphenyl)-N-propyl-1H-pyrazole-5-carboxamide (C14H16ClN3O) 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. 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), 4-Chloro-1-(4-methylphenyl)-N-propyl-1H-pyrazole-5-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.
