Chemical Structure
Description
1-Bromo-4-chloro-2-ethoxy-3-fluorobenzene (CAS 2379321-24-9), molecular formula C8H7BrClFO and molecular weight 253.50 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Bromo-4-chloro-2-ethoxy-3-fluorobenzene (C8H7BrClFO) contains a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 253.50 g/mol, it falls into the medium-molecular-weight range. 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.
