Chemical Structure

(S)-2-mercaptobutanoic acid CAS 1242881-37-3 chemical structure

Description

The occurrence of (S)-2-mercaptobutanoic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(S)-2-mercaptobutanoic acid (CAS 1242881-37-3), molecular formula C4H8O2S and molecular weight 120.17 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (S)-2-mercaptobutanoic acid (C4H8O2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl 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), (S)-2-mercaptobutanoic 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.
