Chemical Structure
Description
The occurrence of Diethyl but-3-en-1-ylphosphonate is closely related to a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Diethyl but-3-en-1-ylphosphonate (CAS 15916-48-0), molecular formula C8H17O3P and molecular weight 192.19 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H17O3P, Diethyl but-3-en-1-ylphosphonate 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 192.19 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.
