4-Chloro-5-(4-methoxyphenyl)-3-perfluopropylpyrazole CAS 1029636-21-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Chloro-5-(4-methoxyphenyl)-3-perfluopropylpyrazole.

4-Chloro-5-(4-methoxyphenyl)-3-perfluopropylpyrazole (CAS 1029636-21-2) is a high-purity analytical reference standard with the molecular formula C13H8ClF7N2O and a molecular weight of 376.66 g/mol.

4-Chloro-5-(4-methoxyphenyl)-3-perfluopropylpyrazole (C13H8ClF7N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/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-5-(4-methoxyphenyl)-3-perfluopropylpyrazole 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.
