Chemical Structure
Description
2-Methyl-2-(pyrrolidin-1-yl)propanoic acid hydrochloride hydrate (CAS 898403-15-1), molecular formula C8H15NO2HClH2O and molecular weight 211.69 g/mol, is a CATO reference standard with documented purity and traceability.
2-Methyl-2-(pyrrolidin-1-yl)propanoic acid hydrochloride hydrate (C8H15NO2HClH2O) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
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.
