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 N-Boc-6-hydroxy-DL-norleucine Methyl Ester.
N-Boc-6-hydroxy-DL-norleucine Methyl Ester (CAS 81505-49-9) is a high-purity analytical reference standard with the molecular formula C12H23NO5 and a molecular weight of 261.31 g/mol.
The molecular framework of N-Boc-6-hydroxy-DL-norleucine Methyl Ester (C12H23NO5) 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.
