Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 161.63 g/mol gives 7-chloro-1H-pyrazolo[4,3-c]pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
7-chloro-1H-pyrazolo[4,3-c]pyridine (CAS 1357946-01-0) is a high-purity analytical reference standard with the molecular formula C6H12ClN3 and a molecular weight of 161.63 g/mol.
7-chloro-1H-pyrazolo[4,3-c]pyridine (C6H12ClN3) contains a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
