Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 199.19 g/mol gives tert-Butyl(dichloromethyl)dimethylsilane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies tert-Butyl(dichloromethyl)dimethylsilane (CAS 138983-08-1), a certified reference material (molecular formula C7H16Cl2Si, MW 199.19 g/mol) for analytical method development and quality control.
tert-Butyl(dichloromethyl)dimethylsilane (C7H16Cl2Si) 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), tert-Butyl(dichloromethyl)dimethylsilane 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.
