Chemical Structure
Description
Triethyl2,2-dichloro-2-phosphonoacetate (CAS 5823-12-1) is a high-purity analytical reference standard with the molecular formula C8H15Cl2O5P and a molecular weight of 293.08 g/mol.
Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Triethyl2,2-dichloro-2-phosphonoacetate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 293.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
