Chemical Structure

2-Diphenylphosphineethyl-functionalized silica gel CAS 1173020-99-9 chemical structure

Description

As a certified reference material (CRM), 2-Diphenylphosphineethyl-functionalized silica gel 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.

2-Diphenylphosphineethyl-functionalized silica gel (CAS 1173020-99-9), molecular formula C14H27PH2OSi and molecular weight 272.44 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-Diphenylphosphineethyl-functionalized silica gel (C14H27PH2OSi) contains organophosphorus functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 272.44 g/mol, it falls into the medium-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.
