Chemical Structure

3-(Ethylthio)propane-1,2-diol CAS 60763-78-2 chemical structure

Description

3-(Ethylthio)propane-1,2-diol (C5H12O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

3-(Ethylthio)propane-1,2-diol (CAS 60763-78-2), molecular formula C5H12O2S and molecular weight 136.21 g/mol, is a CATO reference standard with documented purity and traceability.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
