Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 605.96 g/mol gives Dichlorodioctadecylsilane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dichlorodioctadecylsilane (CAS 67494-12-6), molecular formula C36H74Cl2Si and molecular weight 605.96 g/mol, is a CATO reference standard with documented purity and traceability.
Dichlorodioctadecylsilane (C36H74Cl2Si) contains chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), Dichlorodioctadecylsilane 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.
