Bis(2-ethylhexyl) 3,3'-thiodipropionate CAS 10526-15-5

Description

The occurrence of Bis(2-ethylhexyl) 3,3'-thiodipropionate 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.

Bis(2-ethylhexyl) 3,3'-thiodipropionate (CAS 10526-15-5), molecular formula C22H42O4S and molecular weight 402.63 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Bis(2-ethylhexyl) 3,3'-thiodipropionate (C22H42O4S) 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 402.63 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.

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.

As a certified reference material (CRM), Bis(2-ethylhexyl) 3,3'-thiodipropionate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
