2-(Cyclohexanecarbonyl)-4,5-dihydroxy-3-nitrobenzonitrile CAS 1202893-21-7 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-(Cyclohexanecarbonyl)-4,5-dihydroxy-3-nitrobenzonitrile.

CATO supplies 2-(Cyclohexanecarbonyl)-4,5-dihydroxy-3-nitrobenzonitrile (CAS 1202893-21-7), a certified reference material (molecular formula C14H14N2O5, MW 290.27 g/mol) for analytical method development and quality control.

Based on its molecular formula C14H14N2O5, 2-(Cyclohexanecarbonyl)-4,5-dihydroxy-3-nitrobenzonitrile contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 290.27 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.
