Chemical Structure
Description
As a certified reference material (CRM), Trimethyl(p-tolyl)silane 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.
Trimethyl(p-tolyl)silane (CAS 3728-43-6), molecular formula C10H16Si and molecular weight 164.32 g/mol, is a CATO reference standard with documented purity and traceability.
Trimethyl(p-tolyl)silane (C10H16Si) contains an organic framework. 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.
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.
