Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 1-Hydroxy-4-carboxyl-2,2,6,6-tetramethylpiperidine, Methyl Ester (CAS 439858-36-3), a certified reference material (molecular formula C11H21NO3, MW 215.29 g/mol) for analytical method development and quality control.
Based on its molecular formula C11H21NO3, 1-Hydroxy-4-carboxyl-2,2,6,6-tetramethylpiperidine, Methyl Ester contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 215.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
