1-(2-(4-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)piperazin-1-yl)-2-oxoethoxy)urea CAS 303150-06-3

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.

1-(2-(4-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)piperazin-1-yl)-2-oxoethoxy)urea (CAS 303150-06-3), molecular formula C13H15ClF3N5O3 and molecular weight 381.74 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, 1-(2-(4-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)piperazin-1-yl)-2-oxoethoxy)urea is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 381.74 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).

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.
