Chemical Structure

Isopropenylphosphonicdichloride CAS 3944-27-2 chemical structure

Description

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.

Isopropenylphosphonicdichloride (CAS 3944-27-2) is a high-purity analytical reference standard with the molecular formula C3H7O3PCl and a molecular weight of 157.51 g/mol.

Owing to a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Isopropenylphosphonicdichloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 157.51 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.

CATO manufactures Isopropenylphosphonicdichloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
