Chemical Structure
Description
The occurrence of 2-[(E)-2-(5-Bromo-2-methoxyphenyl)ethenyl]-1-methylpyridin-1-ium iodide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-[(E)-2-(5-Bromo-2-methoxyphenyl)ethenyl]-1-methylpyridin-1-ium iodide (CAS 1047974-84-4), molecular formula C15H15BrNOI and molecular weight 432.09 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-[(E)-2-(5-Bromo-2-methoxyphenyl)ethenyl]-1-methylpyridin-1-ium iodide (C15H15BrNOI) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine/iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 432.09 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 2-[(E)-2-(5-Bromo-2-methoxyphenyl)ethenyl]-1-methylpyridin-1-ium iodide 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.
