4-chloro-3-iodo-1-[(4-methoxyphenyl)methyl]-1H-pyrazolo[4,3-c]pyridine (CAS 1246349-97-2), molecular formula C14H25ClIN3O and molecular weight 413.73 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-chloro-3-iodo-1-[(4-methoxyphenyl)methyl]-1H-pyrazolo[4,3-c]pyridine (C14H25ClIN3O) contains an amide group, a hydroxyl group, an ether linkage, chlorine/iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 413.73 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
