Chemical Structure

1-(2-Chlorophenyl)-3-(4-methoxyphenyl)urea CAS 50906-31-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 276.72 g/mol gives 1-(2-Chlorophenyl)-3-(4-methoxyphenyl)urea distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-(2-Chlorophenyl)-3-(4-methoxyphenyl)urea (CAS 50906-31-5), a certified reference material (molecular formula C14H13ClN2O2, MW 276.72 g/mol) for analytical method development and quality control.

1-(2-Chlorophenyl)-3-(4-methoxyphenyl)urea (C14H13ClN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 1-(2-Chlorophenyl)-3-(4-methoxyphenyl)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.
