N-(5-Chloropentyl)-N'-(2,4-difluorophenyl)urea CAS 647824-96-2

Description

The occurrence of N-(5-Chloropentyl)-N'-(2,4-difluorophenyl)urea is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N-(5-Chloropentyl)-N'-(2,4-difluorophenyl)urea (CAS 647824-96-2), molecular formula C12H15ClF2N2O and molecular weight 276.71 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, N-(5-Chloropentyl)-N'-(2,4-difluorophenyl)urea is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 276.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
