Chemical Structure

Seleno-D,L-ethionine CAS 2578-27-0 chemical structure

Description

The occurrence of Seleno-D,L-ethionine is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Seleno-D,L-ethionine (CAS 2578-27-0), molecular formula C6H13NO2Se and molecular weight 210.13 g/mol, is a CATO reference standard with documented purity and traceability.

Seleno-D,L-ethionine (C6H13NO2Se) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 Seleno-D,L-ethionine 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.
