Chemical Structure
Description
As a certified reference material (CRM), 2-Ethyl-2-(([(9h-fluoren-9-ylmethoxy)carbonyl]amino)methyl)butanoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies 2-Ethyl-2-(([(9h-fluoren-9-ylmethoxy)carbonyl]amino)methyl)butanoic acid (CAS 1553069-09-2), a certified reference material (molecular formula C22H25NO4, MW 367.44 g/mol) for analytical method development and quality control.
The molecular framework of 2-Ethyl-2-(([(9h-fluoren-9-ylmethoxy)carbonyl]amino)methyl)butanoic acid (C22H25NO4) is characterized by a flavonoid core, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
