Ethyl 2-amino-4-(3,4-dimethylphenyl)-5-methylthiophene-3-carboxylate CAS 438220-53-2

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-amino-4-(3,4-dimethylphenyl)-5-methylthiophene-3-carboxylate.

CATO supplies Ethyl 2-amino-4-(3,4-dimethylphenyl)-5-methylthiophene-3-carboxylate (CAS 438220-53-2), a certified reference material (molecular formula C16H19NO2S, MW 289.39 g/mol) for analytical method development and quality control.

The molecular framework of Ethyl 2-amino-4-(3,4-dimethylphenyl)-5-methylthiophene-3-carboxylate (C16H19NO2S) 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 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.

CATO manufactures Ethyl 2-amino-4-(3,4-dimethylphenyl)-5-methylthiophene-3-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.
