Description

4,4,13,13-Tetraethoxy-3,14-dioxa-8,9-dithia-4,13-disilahexadecane (CAS 56706-10-6), molecular formula C18H42O6S2Si2 and molecular weight 474.82 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4,4,13,13-Tetraethoxy-3,14-dioxa-8,9-dithia-4,13-disilahexadecane (C18H42O6S2Si2) 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 0 ring(s) or double-bond equivalent(s). With a molecular weight of 474.82 g/mol, it falls into the moderately-high-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.
