1-(Naphthalen-2-yl)-2-(4-nitrophenyl)ethan-1-one CAS 873411-80-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(Naphthalen-2-yl)-2-(4-nitrophenyl)ethan-1-one.

CATO supplies 1-(Naphthalen-2-yl)-2-(4-nitrophenyl)ethan-1-one (CAS 873411-80-4), a certified reference material (molecular formula C18H13NO3, MW 291.30 g/mol) for analytical method development and quality control.

Based on its molecular formula C18H13NO3, 1-(Naphthalen-2-yl)-2-(4-nitrophenyl)ethan-1-one contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 291.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
