1-Phenyl-3-(4H-1,2,4-triazol-4-yl)urea CAS 35224-76-1

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 1-Phenyl-3-(4H-1,2,4-triazol-4-yl)urea is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 203.20 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).

1-Phenyl-3-(4H-1,2,4-triazol-4-yl)urea (CAS 35224-76-1) is a high-purity analytical reference standard with the molecular formula C9H9N5O and a molecular weight of 203.20 g/mol.

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.

As a certified reference material (CRM), 1-Phenyl-3-(4H-1,2,4-triazol-4-yl)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.
