N-tert-Butoxycarbonyl-D-alanine（Cat No.:R061140）is a derivative of the amino acid D-alanine, modified with a tert-butoxycarbonyl (Boc) protecting group at the nitrogen atom. This modification is commonly used in peptide synthesis to temporarily protect the amino group, preventing unwanted reactions during chain assembly. The compound appears as a white crystalline powder with a melting point of 81-84°C and is sparingly soluble in water but soluble in organic solvents like ethyl acetate and acetic acid. Its chemical formula is C₈H₁₅NO₄, and it has a molecular weight of 189.21 g/mol. Proper handling and storage in a cool, dry place are essential to maintain its stability and reactivity. ​
