(2S,3R)-3-Methoxy-2-((Methoxycarbonyl)aMino)butanoic acid

China [CN]

1. Appearance: White to off-white crystalline powder (typical morphology of chiral amino acid derivatives; higher purity results in better crystallinity); 2. Solubility: Good water solubility (contains carboxylic acid and carbamate groups, which are highly polar), readily soluble in methanol, ethanol, and water, soluble in dichloromethane and ethyl acetate, sparingly soluble in petroleum ether/n-hexane; 3. Stability: Stable under sealed, dry storage at room temperature (recommended ≤25℃), avoid strong acids (Moc group deprotection), strong bases (carboxylic acid salt formation, does not affect the structure), and high temperatures (≥100℃ easily leads to decarboxylation/Moc group decomposition); 4. Melting point: 118~122℃ (characteristic melting point of chiral amino acid derivatives, can be used as an auxiliary indicator of purity).
