O-benzyl-L-methionine toluene-p-sulphonate - Introduction
O-benzyl-L-methionine toluene-p-sulphonate is an organic compound with the chemical formula C13H19NO3S, commonly abbreviated as OMTos. The following is a description of its nature, use, formulation and safety information:
Nature:
O-benzyl-L-methionine toluene-p-sulphonate is a white crystalline solid, soluble in organic solvents such as methanol and ethanol, and insoluble in water.
Use:
O-benzyl-L-methionine toluene-p-sulphonate are often used as amino acid protecting groups in organic synthesis reactions. It can be reacted with amino acids to form protected amino acid derivatives in which methyl and benzyl groups protect the carboxyl and amino groups of methionine. The introduction of this protecting group can improve the selectivity of the reaction, and methionine can be released again by deprotection during the synthesis.
Preparation Method:
O-benzyl-L-methionine toluene-p-sulphonate can be obtained by reacting L-methionine with benzyl alcohol under acidic conditions, and then reacting with p-toluenesulfonic acid to prepare hydrochloride.
Safety Information:
O-benzyl-L-methionine toluene-p-sulphonate has low toxicity, it is still necessary to pay attention to safe operation. Contact with skin, eyes or inhalation of its dust may cause irritation, should avoid direct contact. Appropriate protective measures should be taken during operation, such as wearing gloves and protective glasses.
