NAPHTHALEN-1-YL-ACETIC ACID HYDRAZIDE - Introduction
1-Naphthaleneacehydrazide, also known as 1-Naphthaleneacehydrazide, is an organic compound. Its chemical formula is C12H10N2O and its molecular weight is 198.22g/mol. The following is a description of the nature, use, formulation and safety information of 1-Naphthaleneacehydrazide:
Nature:
The appearance of 1-Naphthaleneacehydrazide was a white to pale yellow crystalline solid. It is combustible, soluble in some organic solvents such as ethanol, ether and methylene chloride, slightly soluble in water. Its melting point is 133-135°C.
Use:
1-Naphthaleneaceethyldrazide is mainly used in the field of pharmaceutical synthesis and organic synthesis. As an azabinone derivative, it can be used to synthesize other organic compounds, such as drugs, dyes and pesticides.
Preparation Method:
The preparation of 1-Naphthaleneacehydrazide is generally obtained by the reaction of naphthoic acid and hydrazine. The specific procedure is as follows: First, the naphthoic acid is dissolved in ethanol, then the hydrazine solution is slowly added, and the reaction is heated. As the reaction proceeds, the product, 1-Naphthaleneacehydrazide, precipitates and crystallizes and can be obtained in pure form by filtration and washing.
Safety Information:
1-Naphthaleneacehydrazide is less toxic, but as a chemical, it still needs to be properly handled and stored. Follow safe practices and wear appropriate protective equipment such as gloves and glasses. Avoid contact with skin and inhalation of dust or vapors. In case of accidental contact or ingestion, please wash the affected area and seek medical help.
