Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 84086-97-5 3,7-Dichloro-8-(dichloromethyl)quinoline DTXSID00517901.
84086-97-5 3,7-Dichloro-8-(dichloromethyl)quinoline DTXSID00517901 (CAS 84086-97-5), molecular formula C10H5Cl4N and molecular weight 280.97 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 84086-97-5 3,7-Dichloro-8-(dichloromethyl)quinoline DTXSID00517901 (C10H5Cl4N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 280.97 g/mol, it falls into the medium-molecular-weight range. 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.
