Phosphorodichloridic Acid CAS 13779-49-2 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies Phosphorodichloridic Acid (CAS 13779-49-2), a certified reference material (molecular formula HCl2O2P, MW 134.89 g/mol) for analytical method development and quality control.

Owing to organophosphorus functionality, chlorine substitution, Phosphorodichloridic Acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 134.89 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.

As a certified reference material (CRM), Phosphorodichloridic Acid 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.
