Chemical Structure
Description
The molecular framework of Fmoc-Val-OH-<SUP>15</SUP>N (C20H33[15N]O4) is characterized by a steroid 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).
Fmoc-Val-OH-<SUP>15</SUP>N (CAS 125700-35-8), molecular formula C20H33[15N]O4 and molecular weight 352.47 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
