6234-01-1 - Introduction

Nature:
H-Glu(OtBu)-OMe . HCl is a solid, white crystalline powder at room temperature. Its melting point is usually in the range of 40-45 degrees Celsius. It is slightly soluble in water and easily soluble in some organic solvents, such as methanol and chloroform.

Use:
H-Glu(OtBu)-OMe . HCl is commonly used as a protecting group in organic synthesis, especially in peptide synthesis. It can protect the hydroxyl (-OH) group of natural amino acids from other unnecessary reactions in the reaction. At the same time, it can also be used as an intermediate in drug research.

Preparation Method:
The preparation method of H-Glu(OtBu)-OMe . HCl is complicated and generally needs to be carried out under laboratory conditions.
First, glutamic acid methyl ester is reacted with p-tert-butylammonium chloride (OtBu-NHCOC1) in a solvent to generate OtBu-L-glutamyl methyl ester. This product is then reacted with hydrochloric acid to produce OtBu-L-glutamyl methyl ester hydrochloride, I .e., H-Glu(OtBu)-OMe. HCl.

Safety Information:
H-Glu(OtBu)-OMe . HCl has high safety, but the following matters still need to be paid attention:
1. use to wear appropriate personal protective equipment, such as gloves, protective glasses.
2. Avoid inhaling the dust of the compound and avoid contact with skin and eyes.
3. avoid ingestion during use. If ingested or exposed, seek medical attention immediately and show relevant information.
4. Keep away from fire and oxidant, and store in a dry and cool place.
