Chemical Structure
Description
CATO supplies p-nitrobenzaldehyde-2,3,5,6-d<SUB>4</SUB> (CAS 1020718-72-2), a certified reference material (molecular formula C7H7D4NO3, MW 161.19 g/mol) for analytical method development and quality control.
Based on its molecular formula C7H7D4NO3, p-nitrobenzaldehyde-2,3,5,6-d<SUB>4</SUB> contains deuterium isotope labeling, 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 161.19 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.
