Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (((9H-Fluoren-9-yl)methoxy)carbonyl)aspartic acid.
(((9H-Fluoren-9-yl)methoxy)carbonyl)aspartic acid (CAS 136083-73-3), molecular formula C19H17NO6 and molecular weight 355.34 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (((9H-Fluoren-9-yl)methoxy)carbonyl)aspartic acid (C19H17NO6) 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.
CATO manufactures (((9H-Fluoren-9-yl)methoxy)carbonyl)aspartic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
