Chemical Structure
Description
The occurrence of 3-(Chloro(methyl)phosphoryl)propanoyl chloride is closely related to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-(Chloro(methyl)phosphoryl)propanoyl chloride (CAS 15090-24-1) is a high-purity analytical reference standard with the molecular formula C4H7Cl2O2P and a molecular weight of 188.98 g/mol.
Structurally, 3-(Chloro(methyl)phosphoryl)propanoyl chloride (C4H7Cl2O2P) contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, 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 188.98 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
