Compared with other compounds in its class, the molecular weight of 381.88 g/mol gives N-(3-chloro-2-methylphenyl)-3-methyl-1-phenyl-1H-thieno[2,3-c]pyrazole-5-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
N-(3-chloro-2-methylphenyl)-3-methyl-1-phenyl-1H-thieno[2,3-c]pyrazole-5-carboxamide (CAS 328548-57-8) is a high-purity analytical reference standard with the molecular formula C20H16ClN3OS and a molecular weight of 381.88 g/mol.
N-(3-chloro-2-methylphenyl)-3-methyl-1-phenyl-1H-thieno[2,3-c]pyrazole-5-carboxamide (C20H16ClN3OS) 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.
