Chemical Structure

2,2-Dimethyl-6-nitrochroman-4-one CAS 111478-49-0 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 2,2-Dimethyl-6-nitrochroman-4-one.

CATO supplies 2,2-Dimethyl-6-nitrochroman-4-one (CAS 111478-49-0), a certified reference material (molecular formula C11H11NO4, MW 221.21 g/mol) for analytical method development and quality control.

Based on its molecular formula C11H11NO4, 2,2-Dimethyl-6-nitrochroman-4-one contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 221.21 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.

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.
