Chemical Structure
Description
The occurrence of Isooctadecenylsuccinic Anhydride(mixture of branched chain isomers) is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Isooctadecenylsuccinic Anhydride(mixture of branched chain isomers) (CAS 58239-72-8) is a high-purity analytical reference standard with the molecular formula C22H38O3 and a molecular weight of 350.54 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, Isooctadecenylsuccinic Anhydride(mixture of branched chain isomers) is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 350.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Isooctadecenylsuccinic Anhydride(mixture of branched chain isomers) 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.
