Chemical Structure
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.
5-(Imidazo[1,2-a]pyridin-2-yl)-2-methylaniline (CAS 1706441-66-8), molecular formula C14H13N3 and molecular weight 223.27 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(Imidazo[1,2-a]pyridin-2-yl)-2-methylaniline (C14H13N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
