Boc-Asp-OtBu - Introduction
Boc-Asp-OtBu, commonly known as Boc-Asp-OtBu, is an organic compound. The following is an introduction to some of its properties, uses, formulation and safety information:
Nature:
-Appearance: Colorless crystalline or powdery objects.
-Molecular formula: C≡H≡NO-7.
-Molecular weight: 393.47g/mol.
-Melting point: about 68-70°C.
-Solubility: Soluble in some organic solvents, such as dimethylformamide (DMF) and dichloromethane (DCM).
Use:
- Boc-Asp-OtBu is a commonly used protecting group, often used in the synthesis of peptides and protein compounds. It can protect the carboxyl and amino groups of glutamic acid (Asp) and prevent accidental reactions and degradation.
- Boc-Asp-OtBu can also be used as reaction intermediates in organic synthesis, such as in peptide synthesis and drug synthesis.
Preparation Method:
-Usually, Boc-Asp-OtBu is prepared by reacting the corresponding amino acid (L-glutamic acid) with a tert-butyl protecting group (Boc) and a tert-butoxycarbonyl protecting group (OtBu). The reaction is carried out under suitable conditions, for example by addition of an activator such as 1-(trimethylsilyl)-1H-pyrazol-3-one (TBTU) or N,N'-diisopropylmethylamide (DIPCDI) in an organic solvent.
Safety Information:
- Boc-Asp-OtBu with low toxicity.
-Because it is an organic compound, avoid inhaling dust or contact with skin and eyes.
-When operating, you need to follow appropriate laboratory safety measures, such as wearing protective gloves and eye protection.
-When storing, it should be kept in a cool, dry place, and away from fire and oxidizing agents.
