Description
CATO manufactures 2-Oxo-2-(phenylamino)ethyl 3-methylthiophene-2-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
2-Oxo-2-(phenylamino)ethyl 3-methylthiophene-2-carboxylate (CAS 380567-83-9), molecular formula C14H13NO3S and molecular weight 275.32 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Oxo-2-(phenylamino)ethyl 3-methylthiophene-2-carboxylate (C14H13NO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
