Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-(4-Methoxyphenyl)-1-phenyl-5-(m-tolyl)-1H-pyrazole (CAS 681293-63-0) is a high-purity analytical reference standard with the molecular formula C23H20N2O and a molecular weight of 340.42 g/mol.
3-(4-Methoxyphenyl)-1-phenyl-5-(m-tolyl)-1H-pyrazole (C23H20N2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. 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.
As a certified reference material (CRM), 3-(4-Methoxyphenyl)-1-phenyl-5-(m-tolyl)-1H-pyrazole 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.
