Chemical Structure

Diethyl (4-hydroxy-2,5-dimethylphenyl) phosphate CAS 1420992-07-9 chemical structure

Description

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.

CATO supplies Diethyl (4-hydroxy-2,5-dimethylphenyl) phosphate (CAS 1420992-07-9), a certified reference material (molecular formula C12H19O5P, MW 274.25 g/mol) for analytical method development and quality control.

Structurally, Diethyl (4-hydroxy-2,5-dimethylphenyl) phosphate (C12H19O5P) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 274.25 g/mol, it falls into the medium-molecular-weight range. 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.
