Chemical Structure
Description
The occurrence of Sodium 1-hydroxyethane-1-sulfonate is closely related to a sulfone group, a carboxylic acid group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Sodium 1-hydroxyethane-1-sulfonate (CAS 918-04-7) is a high-purity analytical reference standard with the molecular formula C2H5O4SNa and a molecular weight of 148.11 g/mol.
The molecular framework of Sodium 1-hydroxyethane-1-sulfonate (C2H5O4SNa) is characterized by a sulfone group, a carboxylic acid group, an ether linkage. 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), Sodium 1-hydroxyethane-1-sulfonate 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.
