Chemical Structure
Description
2-((Carboxymethyl)thio)propanoic acid (CAS 14618-66-7) is a high-purity analytical reference standard with the molecular formula C5H8O4S and a molecular weight of 164.18 g/mol.
The molecular framework of 2-((Carboxymethyl)thio)propanoic acid (C5H8O4S) is characterized by a carbohydrate-derived structure, a sulfone group. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
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), 2-((Carboxymethyl)thio)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.
