Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Bromo-1,3-difluoro-2-(methoxymethoxy)benzene.
5-Bromo-1,3-difluoro-2-(methoxymethoxy)benzene (CAS 623148-02-7) is a high-purity analytical reference standard with the molecular formula C8H7BrF2O2 and a molecular weight of 253.04 g/mol.
5-Bromo-1,3-difluoro-2-(methoxymethoxy)benzene (C8H7BrF2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
