Chemical Structure
Description
69045-83-6 H56Z8J98WV 2,3-Dichloro-5-(trichloromethyl)pyridine Pyridine, 2,3-dichloro-5-(trichloromethyl)- UNII-H56Z8J98WV (C6H2Cl5N) contains a nitrile group, chlorine 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).
69045-83-6 H56Z8J98WV 2,3-Dichloro-5-(trichloromethyl)pyridine Pyridine, 2,3-dichloro-5-(trichloromethyl)- UNII-H56Z8J98WV (CAS 69045-83-6) is a high-purity analytical reference standard with the molecular formula C6H2Cl5N and a molecular weight of 265.35 g/mol.
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.
