Chemical Structure
Description
The occurrence of 1-(2,6-Dichlorophenyl)-3-methyl-1H-pyrazol-5(4H)-one 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.
1-(2,6-Dichlorophenyl)-3-methyl-1H-pyrazol-5(4H)-one (CAS 14580-17-7), molecular formula C10H8Cl2N2O and molecular weight 243.09 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(2,6-Dichlorophenyl)-3-methyl-1H-pyrazol-5(4H)-one (C10H8Cl2N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-(2,6-Dichlorophenyl)-3-methyl-1H-pyrazol-5(4H)-one 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.
