Description
As a certified reference material (CRM), Dodecamethylcyclohexasiloxane-d36 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.
CATO supplies Dodecamethylcyclohexasiloxane-d36 (CAS 206533-14-4), a certified reference material (molecular formula C12D36O6Si6, MW 481.15 g/mol) for analytical method development and quality control.
Dodecamethylcyclohexasiloxane-d36 (C12D36O6Si6) contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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.
