Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Bromo-1-methylpyridin-1-ium iodide.
2-Bromo-1-methylpyridin-1-ium iodide (CAS 52693-56-8), molecular formula C6H7BrNI and molecular weight 299.93 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Bromo-1-methylpyridin-1-ium iodide (C6H7BrNI) is characterized by a nitrile group, bromine/iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
CATO manufactures 2-Bromo-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.
