Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 2-(4-chlorophenylamino)-2-oxoacetate.
Ethyl 2-(4-chlorophenylamino)-2-oxoacetate (CAS 5397-14-8), molecular formula C10H10ClNO3 and molecular weight 227.64 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H10ClNO3, Ethyl 2-(4-chlorophenylamino)-2-oxoacetate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 227.64 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
