Description

Compared with other compounds in its class, the molecular weight of 178.21 g/mol gives 3,3'-Thiodipropionic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3,3'-Thiodipropionic Acid (CAS 111-17-1), molecular formula C6H10O4S and molecular weight 178.21 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3,3'-Thiodipropionic Acid (C6H10O4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 178.21 g/mol, it falls into the medium-molecular-weight range.

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.
