CATO supplies methyl 5-{[(tert-butoxy)carbonyl]amino}-1,2-oxazole-3-carboxylate (CAS 1779756-98-7), a certified reference material (molecular formula C10H14N2O5, MW 242.23 g/mol) for analytical method development and quality control.
The molecular framework of methyl 5-{[(tert-butoxy)carbonyl]amino}-1,2-oxazole-3-carboxylate (C10H14N2O5) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
