Chemical Structure

(3-Fluoro-4-methylphenyl)urea CAS 953736-14-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 168.17 g/mol gives (3-Fluoro-4-methylphenyl)urea distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (3-Fluoro-4-methylphenyl)urea (CAS 953736-14-6), a certified reference material (molecular formula C8H9FN2O, MW 168.17 g/mol) for analytical method development and quality control.

The molecular framework of (3-Fluoro-4-methylphenyl)urea (C8H9FN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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.

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), (3-Fluoro-4-methylphenyl)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.
