Chemical Structure
Description
The occurrence of Sodium 2,3-dimercapto-1-propanesulfonate 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.
Sodium 2,3-dimercapto-1-propanesulfonate (CAS 4076-02-2), molecular formula C3H7O3S3Na and molecular weight 210.26 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Sodium 2,3-dimercapto-1-propanesulfonate (C3H7O3S3Na) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 210.26 g/mol, it falls into the medium-molecular-weight range.
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.
