Chemical Structure
Description
The occurrence of 4186-14-5 5762AB C12H16Si Trimethyl(p-tolylethynyl)silane is closely related to an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4186-14-5 5762AB C12H16Si Trimethyl(p-tolylethynyl)silane (CAS 4186-14-5), a certified reference material (molecular formula C12H16Si, MW 188.34 g/mol) for analytical method development and quality control.
4186-14-5 5762AB C12H16Si Trimethyl(p-tolylethynyl)silane (C12H16Si) contains an aromatic ring system. 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), 4186-14-5 5762AB C12H16Si Trimethyl(p-tolylethynyl)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.
