Chemical Structure
Description
Owing to chlorine/iodine substitution, an aromatic ring system, 2-Chloro-6-iodonaphthalene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 288.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
2-Chloro-6-iodonaphthalene (CAS 858024-79-0), molecular formula C10H6ClI and molecular weight 288.51 g/mol, is a CATO reference standard with documented purity and traceability.
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.
