Chemical Structure
Description
1,1-difluoro-N-[1-(piperidin-4-yl)-1H-pyrazol-4-yl]methanesulfonamide hydrochloride (CAS 1797883-28-3) is a high-purity analytical reference standard with the molecular formula C9H14F2N4O2SHCl and a molecular weight of 316.75 g/mol.
Structurally, 1,1-difluoro-N-[1-(piperidin-4-yl)-1H-pyrazol-4-yl]methanesulfonamide hydrochloride (C9H14F2N4O2SHCl) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine 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 316.75 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.
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.
