Chemical Structure
Description
The occurrence of (Oxybis(2,1-phenylene))bis(di-tert-butylphosphine) is closely related to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(Oxybis(2,1-phenylene))bis(di-tert-butylphosphine) (CAS 338800-12-7), molecular formula C28H44OP2 and molecular weight 458.60 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, (Oxybis(2,1-phenylene))bis(di-tert-butylphosphine) is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 458.60 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.
As a certified reference material (CRM), (Oxybis(2,1-phenylene))bis(di-tert-butylphosphine) 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.
