Chemical Structure
Description
The occurrence of (4-Bromo-3-(trifluoromethyl)phenyl)hydrazine is closely related to a nitrile group, fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(4-Bromo-3-(trifluoromethyl)phenyl)hydrazine (CAS 77992-51-9) is a high-purity analytical reference standard with the molecular formula C7H6BrF3N2 and a molecular weight of 255.04 g/mol.
Owing to a nitrile group, fluorine/bromine substitution, an aromatic ring system, (4-Bromo-3-(trifluoromethyl)phenyl)hydrazine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 255.04 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures (4-Bromo-3-(trifluoromethyl)phenyl)hydrazine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
