Chemical Structure

Diethyl ethynylphosphonate CAS 4851-51-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Diethyl ethynylphosphonate.

Diethyl ethynylphosphonate (CAS 4851-51-8) is a high-purity analytical reference standard with the molecular formula C6H11O3P and a molecular weight of 162.12 g/mol.

Based on its molecular formula C6H11O3P, Diethyl ethynylphosphonate contains a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 162.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
