Chemical Structure

1-(Triphenylsilyl)propan-1-one CAS 2294-99-7 chemical structure

Description

1-(Triphenylsilyl)propan-1-one (CAS 2294-99-7) is a high-purity analytical reference standard with the molecular formula C21H20OSi and a molecular weight of 316.47 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, 1-(Triphenylsilyl)propan-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 316.47 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures 1-(Triphenylsilyl)propan-1-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
