Chemical Structure

3-Fluoro-2-iodo-4-methylpyridine CAS 153035-05-3 chemical structure

Description

The occurrence of 3-Fluoro-2-iodo-4-methylpyridine is closely related to a nitrile group, fluorine/iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-Fluoro-2-iodo-4-methylpyridine (CAS 153035-05-3), a certified reference material (molecular formula C6H5FIN, MW 237.01 g/mol) for analytical method development and quality control.

Owing to a nitrile group, fluorine/iodine substitution, an aromatic ring system, 3-Fluoro-2-iodo-4-methylpyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 237.01 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.

As a certified reference material (CRM), 3-Fluoro-2-iodo-4-methylpyridine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
