Chemical Structure
Description
The occurrence of Dioctadecyl 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.
Dioctadecyl 3,3＇-Thiodipropionate (CAS 693-36-7) is a high-purity analytical reference standard with the molecular formula C42H82O4S and a molecular weight of 683.16 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Dioctadecyl 3,3＇-Thiodipropionate is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 683.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Dioctadecyl 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.
