3-Methyl-1-phenyl-4-(thiophene-2-carbonyl)-1H-pyrazol-5(4H)-one CAS 29665-05-2

Description

Compared with other compounds in its class, the molecular weight of 284.33 g/mol gives 3-Methyl-1-phenyl-4-(thiophene-2-carbonyl)-1H-pyrazol-5(4H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Methyl-1-phenyl-4-(thiophene-2-carbonyl)-1H-pyrazol-5(4H)-one (CAS 29665-05-2), molecular formula C15H12N2O2S and molecular weight 284.33 g/mol, is a CATO reference standard with documented purity and traceability.

3-Methyl-1-phenyl-4-(thiophene-2-carbonyl)-1H-pyrazol-5(4H)-one (C15H12N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
