3-amino-1-(2-chloro-5-methoxyphenyl)urea CAS 743397-09-3

Description

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.

CATO supplies 3-amino-1-(2-chloro-5-methoxyphenyl)urea (CAS 743397-09-3), a certified reference material (molecular formula C8H10ClN3O2, MW 215.64 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, 3-amino-1-(2-chloro-5-methoxyphenyl)urea is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 215.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

As a certified reference material (CRM), 3-amino-1-(2-chloro-5-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.
