Description

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.

(1-(5-CARBOXYPENTYL)-3,3-DIMETHYL-3H-INDOL-1-IUM-2-YL)METHANIDE HYDROBROMIDE 28489-28-3 4-Fluoro-3-methylpyridine AS04869 (CAS 28489-28-3) is a high-purity analytical reference standard with the molecular formula C6H6FN and a molecular weight of 111.12 g/mol.

The molecular framework of (1-(5-CARBOXYPENTYL)-3,3-DIMETHYL-3H-INDOL-1-IUM-2-YL)METHANIDE HYDROBROMIDE 28489-28-3 4-Fluoro-3-methylpyridine AS04869 (C6H6FN) is characterized by a nitrile group, fluorine substitution, an aromatic ring system. 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.

As a certified reference material (CRM), (1-(5-CARBOXYPENTYL)-3,3-DIMETHYL-3H-INDOL-1-IUM-2-YL)METHANIDE HYDROBROMIDE 28489-28-3 4-Fluoro-3-methylpyridine AS04869 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.
