Chemical Structure
Description
CATO supplies (2e)-4-{[(tert-butoxy)carbonyl]amino}-4-methylpent-2-enoic acid (CAS 181645-94-3), a certified reference material (molecular formula C11H19NO4, MW 229.27 g/mol) for analytical method development and quality control.
The molecular framework of (2e)-4-{[(tert-butoxy)carbonyl]amino}-4-methylpent-2-enoic acid (C11H19NO4) 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.
