N,N’-bis(3,5-dichlorophenyl)urea CAS 73439-19-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 350.03 g/mol gives N,N’-bis(3,5-dichlorophenyl)urea distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies N,N’-bis(3,5-dichlorophenyl)urea (CAS 73439-19-7), a certified reference material (molecular formula C13H8Cl4N2O, MW 350.03 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, N,N’-bis(3,5-dichlorophenyl)urea is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 350.03 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), N,N’-bis(3,5-dichlorophenyl)urea 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.
