Chemical Structure
Description
(4-(Trifluoromethyl)phenyl)zinc bromide, 0.50 M in THF (CAS 198345-82-3), molecular formula BrZnC7H4F3 and molecular weight 290.39 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a salt form, fluorine/bromine substitution, an aromatic ring system, (4-(Trifluoromethyl)phenyl)zinc bromide, 0.50 M in THF is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 290.39 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.
As a certified reference material (CRM), (4-(Trifluoromethyl)phenyl)zinc bromide, 0.50 M in THF 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.
