The occurrence of Nonenylsuccinic Anhydride (mixture of branched chain isomers) is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Nonenylsuccinic Anhydride (mixture of branched chain isomers) (CAS 64545-80-8), molecular formula C13H20O3 and molecular weight 224.30 g/mol, is a CATO reference standard with documented purity and traceability.
Nonenylsuccinic Anhydride (mixture of branched chain isomers) (C13H20O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Nonenylsuccinic 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.
