Chemical Structure
Description
2-Chloroethyl phosphorodichloridate (CAS 1455-05-6) is a high-purity analytical reference standard with the molecular formula C2H4Cl3O2P and a molecular weight of 197.38 g/mol.
Owing to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 2-Chloroethyl phosphorodichloridate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 197.38 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.
