Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,3'-Oxybis(3-(chloromethyl)-1,1,1,5,5,5-hexamethyltrisiloxane).
3,3'-Oxybis(3-(chloromethyl)-1,1,1,5,5,5-hexamethyltrisiloxane) (CAS 17909-34-1) is a high-purity analytical reference standard with the molecular formula C14H40Cl2O5Si6 and a molecular weight of 527.88 g/mol.
3,3'-Oxybis(3-(chloromethyl)-1,1,1,5,5,5-hexamethyltrisiloxane) (C14H40Cl2O5Si6) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 3,3'-Oxybis(3-(chloromethyl)-1,1,1,5,5,5-hexamethyltrisiloxane) 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.
