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 4-chloro-7-methyl-1H-imidazo[4,5-c]pyridine.
CATO supplies 4-chloro-7-methyl-1H-imidazo[4,5-c]pyridine (CAS 18232-95-6), a certified reference material (molecular formula C7H14ClN3, MW 175.66 g/mol) for analytical method development and quality control.
Owing to a nitrile group, chlorine substitution, 4-chloro-7-methyl-1H-imidazo[4,5-c]pyridine is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 175.66 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
