Chemical Structure

Ethyldiethynylphosphine oxide CAS 2855112-40-0 chemical structure

Description

The occurrence of Ethyldiethynylphosphine oxide is closely related to organophosphorus functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyldiethynylphosphine oxide (CAS 2855112-40-0) is a high-purity analytical reference standard with the molecular formula C6H7OP and a molecular weight of 126.09 g/mol.

Ethyldiethynylphosphine oxide (C6H7OP) contains organophosphorus functionality, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
