Chemical Structure
Description
Dichloroethylmethylsilane (CAS 4525-44-4), molecular formula C3H8Cl2Si and molecular weight 143.09 g/mol, is a CATO reference standard with documented purity and traceability.
Dichloroethylmethylsilane (C3H8Cl2Si) 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.
As a certified reference material (CRM), Dichloroethylmethylsilane 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.
