Chemical Structure
Description
The occurrence of N-(tert-Butoxycarbonyl)-N-methyl-D-leucine is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-(tert-Butoxycarbonyl)-N-methyl-D-leucine (CAS 89536-84-5), molecular formula C12H23NO4 and molecular weight 245.32 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(tert-Butoxycarbonyl)-N-methyl-D-leucine (C12H23NO4) 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
