Description
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.
2-Chloro-N-[(1-methyl-4,5,6,7-tetrahydro-1H-pyrazolo-[4,3-c]pyridin-3-yl)methyl]-N-phenylbenzamide hydrochloride (CAS 1354550-72-3) is a high-purity analytical reference standard with the molecular formula C21H21ClN4OHCl and a molecular weight of 417.33 g/mol.
2-Chloro-N-[(1-methyl-4,5,6,7-tetrahydro-1H-pyrazolo-[4,3-c]pyridin-3-yl)methyl]-N-phenylbenzamide hydrochloride (C21H21ClN4OHCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
