(2R,3S,4S,5R)-2-(ethylthio)-2,5-bis(hydroxymethyl)tetrahydrofuran-3,4-diol CAS 80763-60-6

Description

The occurrence of (2R,3S,4S,5R)-2-(ethylthio)-2,5-bis(hydroxymethyl)tetrahydrofuran-3,4-diol 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.

(2R,3S,4S,5R)-2-(ethylthio)-2,5-bis(hydroxymethyl)tetrahydrofuran-3,4-diol (CAS 80763-60-6), molecular formula C8H16O5S and molecular weight 224.27 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (2R,3S,4S,5R)-2-(ethylthio)-2,5-bis(hydroxymethyl)tetrahydrofuran-3,4-diol (C8H16O5S) 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
