Chemical Structure
Description
The occurrence of (R)-2-Acetamido-3-(nitrosothio)propanoic acid is closely related to a carbohydrate-derived structure, an amide group, a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (R)-2-Acetamido-3-(nitrosothio)propanoic acid (CAS 56577-02-7), a certified reference material (molecular formula C5H8N2O4S, MW 192.19 g/mol) for analytical method development and quality control.
(R)-2-Acetamido-3-(nitrosothio)propanoic acid (C5H8N2O4S) contains a carbohydrate-derived structure, an amide group, a sulfone group. It is notably hygroscopic, 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).
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), (R)-2-Acetamido-3-(nitrosothio)propanoic acid 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.
