Chemical Structure
Description
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.
Methyl 3-(2-(2-((4-chlorophenyl)sulfonyl)-1-methylhydrazinyl)acetamido)thiophene-2-carboxylate (CAS 861212-55-7), molecular formula C15H16ClN3O5S2 and molecular weight 417.89 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl 3-(2-(2-((4-chlorophenyl)sulfonyl)-1-methylhydrazinyl)acetamido)thiophene-2-carboxylate (C15H16ClN3O5S2) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
