Chemical Structure
Description
As a certified reference material (CRM), Hexachlorodisilane 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 Hexachlorodisilane (CAS 13465-77-5), a certified reference material (molecular formula Cl6Si2, MW 268.89 g/mol) for analytical method development and quality control.
Hexachlorodisilane (Cl6Si2) contains chlorine substitution. Halogen substitution raises its density and boiling point; 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.
