PLM4VBZ8MZ 4090-55-5 2-Chloro-5,5-dimethyl-1,3,2-dioxaphosphorinane 2-oxide 1,3,2-Dioxaphosphorinane, 2-chloro-5,5-dimethyl-, 2-oxide EINECS 223-831-2 Phosphorochloridic acid, cyclic (2,2-dimethyltrimethylene) ester UNII-PLM4VBZ8MZ (CAS 4090-55-5), molecular formula C5H10ClO3P and molecular weight 184.56 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of PLM4VBZ8MZ 4090-55-5 2-Chloro-5,5-dimethyl-1,3,2-dioxaphosphorinane 2-oxide 1,3,2-Dioxaphosphorinane, 2-chloro-5,5-dimethyl-, 2-oxide EINECS 223-831-2 Phosphorochloridic acid, cyclic (2,2-dimethyltrimethylene) ester UNII-PLM4VBZ8MZ (C5H10ClO3P) is characterized by a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
