Chemical Structure

Ethyl Thiooxamate CAS 16982-21-1 chemical structure

Description

Ethyl Thiooxamate (CAS 16982-21-1) is a high-purity analytical reference standard with the molecular formula C4H7NO2S and a molecular weight of 133.17 g/mol.

The molecular framework of Ethyl Thiooxamate (C4H7NO2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), Ethyl Thiooxamate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
