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 948294-46-0 6-Bromo-2-chloro-3-(2-chloroethyl)quinoline DTXSID50588944.
948294-46-0 6-Bromo-2-chloro-3-(2-chloroethyl)quinoline DTXSID50588944 (CAS 948294-46-0), molecular formula C11H18BrCl2N and molecular weight 315.08 g/mol, is a CATO reference standard with documented purity and traceability.
948294-46-0 6-Bromo-2-chloro-3-(2-chloroethyl)quinoline DTXSID50588944 (C11H18BrCl2N) contains a nitrile group, chlorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
