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.
6-chloro-3-iodo-1H-pyrazolo[4,3-c]pyridine (CAS 1260672-72-7), molecular formula C6H11ClIN3 and molecular weight 287.53 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C6H11ClIN3, 6-chloro-3-iodo-1H-pyrazolo[4,3-c]pyridine contains a nitrile group, chlorine/iodine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 287.53 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
