2-Amino-5-(4-chlorophenyl)-6-ethylpyrimidin-4(3H)-one trifluoroacetate salt CAS 91396-20-2 chemical structure

Description

The occurrence of 2-Amino-5-(4-chlorophenyl)-6-ethylpyrimidin-4(3H)-one trifluoroacetate salt 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.

2-Amino-5-(4-chlorophenyl)-6-ethylpyrimidin-4(3H)-one trifluoroacetate salt (CAS 91396-20-2) is a high-purity analytical reference standard with the molecular formula C12H12ClN3OC2HF3O2 and a molecular weight of 363.72 g/mol.

The molecular framework of 2-Amino-5-(4-chlorophenyl)-6-ethylpyrimidin-4(3H)-one trifluoroacetate salt (C12H12ClN3OC2HF3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine 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), 2-Amino-5-(4-chlorophenyl)-6-ethylpyrimidin-4(3H)-one trifluoroacetate salt 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.
