Description
As a certified reference material (CRM), (2-Isopropoxy-2-oxo-ethyl)-triphenyl-phosphonium;chloride 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-Isopropoxy-2-oxo-ethyl)-triphenyl-phosphonium;chloride (CAS 104718-15-2) is a high-purity analytical reference standard with the molecular formula C23H24O2PCl and a molecular weight of 398.87 g/mol.
Owing to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution, (2-Isopropoxy-2-oxo-ethyl)-triphenyl-phosphonium;chloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 398.87 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.
