2-Thienylcarbamic Acid Ethyl Ester CAS 105995-16-2 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 2-Thienylcarbamic Acid Ethyl Ester (CAS 105995-16-2), a certified reference material (molecular formula C7H9NO2S, MW 171.22 g/mol) for analytical method development and quality control.

2-Thienylcarbamic Acid Ethyl Ester (C7H9NO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO manufactures 2-Thienylcarbamic Acid Ethyl Ester 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.
