Ethyl 5-amino-4-bromo-1-(2,2,2-trifluoroethyl)-1H-pyrazole-3-carboxylate CAS 1427023-16-2

Description

The occurrence of Ethyl 5-amino-4-bromo-1-(2,2,2-trifluoroethyl)-1H-pyrazole-3-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl 5-amino-4-bromo-1-(2,2,2-trifluoroethyl)-1H-pyrazole-3-carboxylate (CAS 1427023-16-2) is a high-purity analytical reference standard with the molecular formula C8H9BrF3N3O2 and a molecular weight of 316.08 g/mol.

The molecular framework of Ethyl 5-amino-4-bromo-1-(2,2,2-trifluoroethyl)-1H-pyrazole-3-carboxylate (C8H9BrF3N3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Ethyl 5-amino-4-bromo-1-(2,2,2-trifluoroethyl)-1H-pyrazole-3-carboxylate 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.
