Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-[5-(2,4-Dichlorophenyl)-1H-pyrazol-1-yl]-4-(4-methoxyphenyl)-1,3-thiazole.
2-[5-(2,4-Dichlorophenyl)-1H-pyrazol-1-yl]-4-(4-methoxyphenyl)-1,3-thiazole (CAS 956977-62-1), molecular formula C19H13Cl2N3OS and molecular weight 402.30 g/mol, is a CATO reference standard with documented purity and traceability.
2-[5-(2,4-Dichlorophenyl)-1H-pyrazol-1-yl]-4-(4-methoxyphenyl)-1,3-thiazole (C19H13Cl2N3OS) contains a steroid core, an amide group, sulfur-containing functionality, 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.
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), 2-[5-(2,4-Dichlorophenyl)-1H-pyrazol-1-yl]-4-(4-methoxyphenyl)-1,3-thiazole 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.
