As a certified reference material (CRM), Hexaphenylcyclotrisiloxane 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 Hexaphenylcyclotrisiloxane (CAS 512-63-0), a certified reference material (molecular formula C36H30O3Si3, MW 594.88 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Hexaphenylcyclotrisiloxane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 594.88 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
