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-Fluoro-5-iodopyridine.
2-Fluoro-5-iodopyridine (CAS 171197-80-1), molecular formula C5H9FIN and molecular weight 229.03 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to fluorine/iodine substitution, 2-Fluoro-5-iodopyridine is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 229.03 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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-Fluoro-5-iodopyridine 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.
