Bis((dibutoxyphosphorothioyl)thio)zinc CAS 6990-43-8 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Bis((dibutoxyphosphorothioyl)thio)zinc (CAS 6990-43-8) is a high-purity analytical reference standard with the molecular formula C16H36O4P2S4Zn and a molecular weight of 548.07 g/mol.

Structurally, Bis((dibutoxyphosphorothioyl)thio)zinc (C16H36O4P2S4Zn) contains a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of -1.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 548.07 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
