Description
As a certified reference material (CRM), Thiobis(ethane-2,1-diyl) didodecanoate 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.
Thiobis(ethane-2,1-diyl) didodecanoate (CAS 4275-31-4) is a high-purity analytical reference standard with the molecular formula C28H54O4S and a molecular weight of 486.79 g/mol.
The molecular framework of Thiobis(ethane-2,1-diyl) didodecanoate (C28H54O4S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
