Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Bromomethoxy-2,3,5,6-tetrafluorobenzotrifluoride.
CATO supplies 4-Bromomethoxy-2,3,5,6-tetrafluorobenzotrifluoride (CAS 883521-27-5), a certified reference material (molecular formula C8H2BrF7O, MW 326.99 g/mol) for analytical method development and quality control.
4-Bromomethoxy-2,3,5,6-tetrafluorobenzotrifluoride (C8H2BrF7O) contains a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
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.
