1-(2-Chlorophenyl)-5-methyl-1H-pyrazol-3(2H)-one CAS 14580-10-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2-Chlorophenyl)-5-methyl-1H-pyrazol-3(2H)-one.

1-(2-Chlorophenyl)-5-methyl-1H-pyrazol-3(2H)-one (CAS 14580-10-0) is a high-purity analytical reference standard with the molecular formula C10H9ClN2O and a molecular weight of 208.64 g/mol.

1-(2-Chlorophenyl)-5-methyl-1H-pyrazol-3(2H)-one (C10H9ClN2O) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

CATO manufactures 1-(2-Chlorophenyl)-5-methyl-1H-pyrazol-3(2H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
