Chemical Structure
Description
CATO supplies (S)-tert-Butyl 8-(hydroxymethyl)-1,4-dioxa-7-azaspiro[4.4]nonane-7-carboxylate (CAS 1447616-14-9), a certified reference material (molecular formula C12H21NO5, MW 259.30 g/mol) for analytical method development and quality control.
(S)-tert-Butyl 8-(hydroxymethyl)-1,4-dioxa-7-azaspiro[4.4]nonane-7-carboxylate (C12H21NO5) 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.
