Product Name:Boc-N-methyl-L-leucine
English Name:Boc-N-methyl-L-leucine
CAS No.:52355-42-7
Aliases:N-Boc-N-methyl-L-leucine, N-(tert-Butoxycarbonyl)-N-methyl-L-leucine, (2S)-2-[(tert-Butoxycarbonyl)(methyl)amino]-4-methylpentanoic acid, Boc-N-Me-Leu-OH
Molecular Formula:C12H23NO4
Physical Properties:White to off-white crystalline powder; boiling point approx. 350.7°C at 760 mmHg, flash point approx. 165.9°C, relative density approx. 1.0 g/cm³; soluble in methanol, ethanol, chloroform, DMF, DMSO and other organic solvents, slightly soluble in water; store sealed in a dry place at 2–8°C.
Uses:Used as a protected N-methyl amino acid building block in solid-phase peptide synthesis to introduce N-methyl-L-leucine residues. N-methylation can improve the enzymatic stability and membrane permeability of peptides, and is widely used in structure-activity relationship studies of therapeutic peptides. It is also used as an analytical reference reagent and organic synthesis intermediate.
Technical Specifications:
Grade: analytical reagent (AR); purity (HPLC) ≥99.0%
Appearance: white to off-white crystalline powder
Specific rotation: [α]D20 = −24.0° ± 2.0° (c=1, methanol)
Loss on drying ≤0.5%
Packaging: 500 g per bottle
