Chemical Structure
Description
Triphenyl(prop-1-en-1-yl)silane (CAS 18752-22-2), molecular formula C21H20Si and molecular weight 300.47 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Triphenyl(prop-1-en-1-yl)silane (C21H20Si) contains a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 300.47 g/mol, it falls into the moderately-high-molecular-weight range. 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), Triphenyl(prop-1-en-1-yl)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.
