Diethyl(3-hydroxy-4-(prop-2-yn-1-ylamino)phenyl)phosphine oxide CAS 2903922-93-8 chemical structure

Description

The occurrence of Diethyl(3-hydroxy-4-(prop-2-yn-1-ylamino)phenyl)phosphine oxide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Diethyl(3-hydroxy-4-(prop-2-yn-1-ylamino)phenyl)phosphine oxide (CAS 2903922-93-8), a certified reference material (molecular formula C13H18NO2P, MW 251.26 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, Diethyl(3-hydroxy-4-(prop-2-yn-1-ylamino)phenyl)phosphine oxide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 251.26 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), Diethyl(3-hydroxy-4-(prop-2-yn-1-ylamino)phenyl)phosphine oxide 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.
