Chemical Structure

Sodium 2-cyanoethane-1-sulfonate CAS 513-15-5 chemical structure

Description

As a certified reference material (CRM), Sodium 2-cyanoethane-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.

Sodium 2-cyanoethane-1-sulfonate (CAS 513-15-5), molecular formula C3H4NO3SNa and molecular weight 157.12 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C3H4NO3SNa, Sodium 2-cyanoethane-1-sulfonate contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 157.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
