Chemical Structure
Description
The occurrence of Hexamethyl-d18-disiloxane is closely related to deuterium isotope labeling, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Hexamethyl-d18-disiloxane (CAS 19108-55-5), molecular formula C6D18OSi2 and molecular weight 180.49 g/mol, is a CATO reference standard with documented purity and traceability.
Hexamethyl-d18-disiloxane (C6D18OSi2) contains deuterium isotope labeling, a hydroxyl group, an ether linkage, an aromatic ring system. Its physicochemical properties are representative of its class; 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.
CATO manufactures Hexamethyl-d18-disiloxane under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
