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 4-((3-Nitrophenyl)amino)-4-oxobutanoic acid.
4-((3-Nitrophenyl)amino)-4-oxobutanoic acid (CAS 1797-93-9) is a high-purity analytical reference standard with the molecular formula C10H10N2O5 and a molecular weight of 238.20 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 4-((3-Nitrophenyl)amino)-4-oxobutanoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 238.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
