The occurrence of Di-Beta,Beta'-Chloroethylphosphoric Acid is closely related to a carbohydrate-derived structure, a phosphate ester group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Di-Beta,Beta'-Chloroethylphosphoric Acid (CAS 3040-56-0) is a high-purity analytical reference standard with the molecular formula C4H9Cl2O4P and a molecular weight of 222.99 g/mol.
Structurally, Di-Beta,Beta'-Chloroethylphosphoric Acid (C4H9Cl2O4P) contains a carbohydrate-derived structure, a phosphate ester group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of -0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 222.99 g/mol, it falls into the medium-molecular-weight range. 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.
