2055033-05-9 - Introduction
Mal-PEG8-NHS ester(Mal-PEG8-NHS ester) is a chemical reagent with the following properties:
1. nature: the appearance of a white solid, soluble in organic solvents (such as methanol, chloroform, etc.).
2. use: Mal-PEG8-NHS ester is mainly used for modification and functionalization experiments in the field of biochemistry and biomedicine. It is often used as a compound labeling agent, which can react with compounds containing amino groups (such as proteins, peptides, etc.) to form stable amido bonds.
3. preparation method: the preparation of Mal-PEG8-NHS ester generally includes the following steps:
-In the first step, maleimide and octagonal polyethylene glycol (PEG8) are reacted in an appropriate solvent to form maleimide-octagonal polyethylene glycol (Mal-PEG8).
-The second step is to react Mal-PEG8 with N-hydroxysuccinimide ester (NHS ester) under alkaline conditions to generate Mal-PEG8-NHS ester(Mal-PEG8-NHS ester).
4. safety information: when using or handling Mal-PEG8-NHS ester, the following safety measures should be taken:
-Avoid contact with skin, eyes and mucous membranes.
-Wear appropriate protective gloves, goggles and protective clothing during operation.
-Avoid inhalation or ingestion of the compound.
-In case of accidental contact or inhalation, rinse immediately with water and seek medical attention.
Please note that Mal-PEG8-NHS ester is a chemical reagent that is limited to scientific and laboratory use and must be handled in accordance with appropriate practices and safety measures.
