Chemical Structure

1-Chloro-2,5-dihydro-1H-1-phosphol-1-one CAS 822-47-9 chemical structure

Description

As a certified reference material (CRM), 1-Chloro-2,5-dihydro-1H-1-phosphol-1-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

CATO supplies 1-Chloro-2,5-dihydro-1H-1-phosphol-1-one (CAS 822-47-9), a certified reference material (molecular formula C4H6ClOP, MW 136.52 g/mol) for analytical method development and quality control.

Owing to organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution, 1-Chloro-2,5-dihydro-1H-1-phosphol-1-one is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 136.52 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.

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.
