N-([1,1'-Biphenyl]-2-yl)-5-methylisoxazole-3-carboxamide CAS 145440-86-4

Description

The occurrence of N-([1,1'-Biphenyl]-2-yl)-5-methylisoxazole-3-carboxamide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N-([1,1'-Biphenyl]-2-yl)-5-methylisoxazole-3-carboxamide (CAS 145440-86-4), molecular formula C17H14N2O2 and molecular weight 278.31 g/mol, is a CATO reference standard with documented purity and traceability.

N-([1,1'-Biphenyl]-2-yl)-5-methylisoxazole-3-carboxamide (C17H14N2O2) contains a steroid core, an amide 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
