Chemical Structure

Bis(2-chloroethyl) 2-chloroethylphosphonate CAS 6294-34-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 269.49 g/mol gives Bis(2-chloroethyl) 2-chloroethylphosphonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Bis(2-chloroethyl) 2-chloroethylphosphonate (CAS 6294-34-4) is a high-purity analytical reference standard with the molecular formula C6H12Cl3O3P and a molecular weight of 269.49 g/mol.

Owing to a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Bis(2-chloroethyl) 2-chloroethylphosphonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 269.49 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.

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

As a certified reference material (CRM), Bis(2-chloroethyl) 2-chloroethylphosphonate 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.
