((Dibutylstannanediyl)bis(sulfanediyl))bis(ethane-2,1-diyl) bis(2-ethylhexanoate) CAS 68298-37-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including ((Dibutylstannanediyl)bis(sulfanediyl))bis(ethane-2,1-diyl) bis(2-ethylhexanoate).

((Dibutylstannanediyl)bis(sulfanediyl))bis(ethane-2,1-diyl) bis(2-ethylhexanoate) (CAS 68298-37-3), molecular formula C28H56O4S2Sn and molecular weight 639.58 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, ((Dibutylstannanediyl)bis(sulfanediyl))bis(ethane-2,1-diyl) bis(2-ethylhexanoate) (C28H56O4S2Sn) contains a sulfone 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 1 ring(s) or double-bond equivalent(s). With a molecular weight of 639.58 g/mol, it falls into the 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.

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.
