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 1-Bromo-2-(2-bromoethyl)-4-fluorobenzene.
CATO supplies 1-Bromo-2-(2-bromoethyl)-4-fluorobenzene (CAS 1690789-24-2), a certified reference material (molecular formula C8H7Br2F, MW 281.95 g/mol) for analytical method development and quality control.
1-Bromo-2-(2-bromoethyl)-4-fluorobenzene (C8H7Br2F) contains 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.
