Chemical Structure

3-Hydroxy-N-(2-methoxy-5-methylphenyl)naphthalene-2-carboxamide CAS 54079-43-5 chemical structure

Description

The molecular framework of 3-Hydroxy-N-(2-methoxy-5-methylphenyl)naphthalene-2-carboxamide (C19H17NO3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

3-Hydroxy-N-(2-methoxy-5-methylphenyl)naphthalene-2-carboxamide (CAS 54079-43-5), molecular formula C19H17NO3 and molecular weight 307.34 g/mol, is a CATO reference standard with documented purity and traceability.

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.
