N-(4-chloro-2-methylphenyl)-3-hydroxy-2-naphthamide CAS 92-76-2

Description

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.

CATO supplies N-(4-chloro-2-methylphenyl)-3-hydroxy-2-naphthamide (CAS 92-76-2), a certified reference material (molecular formula C18H14ClNO2, MW 311.76 g/mol) for analytical method development and quality control.

Based on its molecular formula C18H14ClNO2, N-(4-chloro-2-methylphenyl)-3-hydroxy-2-naphthamide contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 311.76 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
