Chemical Structure
Description
CATO supplies 4-(Tert-butoxycarbonyl)-1-methylpiperazine-2-carboxylic acid (CAS 851882-93-4), a certified reference material (molecular formula C11H20N2O4, MW 244.29 g/mol) for analytical method development and quality control.
4-(Tert-butoxycarbonyl)-1-methylpiperazine-2-carboxylic acid (C11H20N2O4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
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.
