Introduction
N-(α)-Boc-L-aspartyl is an amino acid derivative, which has the following properties:
Appearance: white to yellowish crystalline powder;
Solubility: soluble in common organic solvents, such as dimethylformamide (DMF) and methanol;
Stability: Stable in a dry environment, but susceptible to moisture in humid conditions, prolonged exposure to high humidity should be avoided.
Its main applications include:
Peptide synthesis: as an intermediate in the synthesis of polypeptides, it can be used to construct peptide chain growth;
Biological research: as an important compound for protein synthesis and research in the laboratory.
The preparation method of N-(α)-Boc-L-aspartoyl acid is generally achieved by reacting L-aspartyl acid with Boc-protective reagent.
Safety information: N-(α)-Boc-L-aspartoyl acid is generally considered to be a compound with low toxicity. As a chemical reagent, safe operating procedures in chemical laboratories should still be followed when handling and using them. Skin contact and inhalation of dust should be avoided. Appropriate personal protective equipment such as lab gloves, glasses, and protective masks should be worn when in use. In case of accidental contact or ingestion, seek medical attention immediately.
