Chemical Structure
Description
3,3-Difluoro-2,2,6,6-tetramethylpiperidin-4-amine dihydrochloride (CAS 1823321-31-8), molecular formula C9H18F2N2HCl and molecular weight 228.71 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H18F2N2HCl, 3,3-Difluoro-2,2,6,6-tetramethylpiperidin-4-amine dihydrochloride contains fluorine/chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 228.71 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
