Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies Ethyl 5-chloro-2-(2-chloroacetamido)-4-phenylthiophene-3-carboxylate (CAS 302582-89-4), a certified reference material (molecular formula C15H13Cl2NO3S, MW 358.24 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 5-chloro-2-(2-chloroacetamido)-4-phenylthiophene-3-carboxylate (C15H13Cl2NO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
