Chemical Structure
Description
The occurrence of (5-Chloro-2-phenoxyphenyl)triphenylsilane is closely related to a steroid core, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(5-Chloro-2-phenoxyphenyl)triphenylsilane (CAS 18866-43-8), molecular formula C30H23ClOSi and molecular weight 463.04 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (5-Chloro-2-phenoxyphenyl)triphenylsilane (C30H23ClOSi) contains a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 19.0, corresponding to approximately 19 ring(s) or double-bond equivalent(s). With a molecular weight of 463.04 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), (5-Chloro-2-phenoxyphenyl)triphenylsilane 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.
