Chemical Structure
Description
Diethylene glycol Diacetate (CAS 628-68-2), molecular formula C8H14O5 and molecular weight 190.19 g/mol, is a CATO reference standard with documented purity and traceability.
Diethylene glycol Diacetate (C8H14O5) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
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), Diethylene glycol Diacetate 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.
