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 Methyl 3-(2-(1-methyl-2-((4-nitrophenyl)sulfonyl)hydrazineyl)acetamido)thiophene-2-carboxylate.
Methyl 3-(2-(1-methyl-2-((4-nitrophenyl)sulfonyl)hydrazineyl)acetamido)thiophene-2-carboxylate (CAS 861212-60-4), molecular formula C15H16N4O7S2 and molecular weight 428.44 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C15H16N4O7S2, Methyl 3-(2-(1-methyl-2-((4-nitrophenyl)sulfonyl)hydrazineyl)acetamido)thiophene-2-carboxylate contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 428.44 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
