Chemical Structure

1-(5-Phenyl-1H-1,2,4-triazol-3-yl)urea CAS 6642-32-6 chemical structure

Description

The molecular framework of 1-(5-Phenyl-1H-1,2,4-triazol-3-yl)urea (C9H9N5O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

1-(5-Phenyl-1H-1,2,4-triazol-3-yl)urea (CAS 6642-32-6) is a high-purity analytical reference standard with the molecular formula C9H9N5O and a molecular weight of 203.20 g/mol.

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

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
