13958-86-6 - Introduction
5-methyl -3, 4-diaminopyridine (abbreviated MEAP) is an organic compound with the chemical formula C7H11N3. The following is a description of the nature, use, method and safety information of MEAP:
Nature:
MEAP is a white to pale yellow solid with an aromatic odor. It is insoluble in water at normal temperature, but soluble in organic solvents such as ethanol and dimethyl sulfoxide. MEAP has a certain alkalinity.
Use:
MEAP is mainly used in the pharmaceutical field as a synthetic raw material for antibiotics and pharmaceutical intermediates. It can also be used as a synthetic intermediate for dyes and pigments, and play the role of a catalyst in organic synthesis. In addition, MEAP can also be used for chemical analysis and laboratory research.
Preparation Method:
MEAP can be prepared by methylation and amination of benzylamine (C6H5CH2NH2). First, benzylamine is reacted with methyl iodide to produce N-benzylmethylbenzylamine (N-benzylmethylbenzylamine). Subsequently, N-benzylmethylbenzylamine is reacted with aqueous ammonia or ammonia gas to give the MEAP product.
Safety Information:
MEAP does not specifically list its risks in some safety data. However, like most organic compounds, it should follow general laboratory safety measures, such as wearing appropriate protective equipment (such as lab clothes, gloves and goggles) and operating in well-ventilated conditions. For industrial production or wider applications, necessary safety assessments and controls are required in accordance with current regulations.
