Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-([1,1'-Biphenyl]-2-yl)-5-methylisoxazole-4-carboxamide.

N-([1,1'-Biphenyl]-2-yl)-5-methylisoxazole-4-carboxamide (CAS 61643-39-8), molecular formula C17H14N2O2 and molecular weight 278.31 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, N-([1,1'-Biphenyl]-2-yl)-5-methylisoxazole-4-carboxamide (C17H14N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 278.31 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
