Chemical Structure
Description
The molecular framework of 6-Bromo-7-iodo-2-naphthalenecarbonitrile (C11H5BrIN) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine/iodine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
6-Bromo-7-iodo-2-naphthalenecarbonitrile (CAS 1042170-69-3) is a high-purity analytical reference standard with the molecular formula C11H5BrIN and a molecular weight of 357.97 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.
CATO manufactures 6-Bromo-7-iodo-2-naphthalenecarbonitrile under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
