2-METHYL-3-NITROPHENYLACETIC ACID - Introduction
2-METHYL-3-NITROPHENYL ACETIC ACID (R4)(2-METHYL-3-NITROPHENYL ACETIC ACID, abbreviated as MNPAA) is an organic compound. Its chemical formula is C9H9NO4.
Nature:
MNPAA is a solid powder with a yellow to yellow-green crystal appearance. It is stable at room temperature, but may explode when exposed to high temperatures, fire sources or oxidants.
Use:
MNPAA is an important organic synthesis intermediate, which has a wide range of applications in the pharmaceutical, pesticide and dye industries. It can be used to synthesize important chemicals such as pharmaceuticals, pesticides and pigments.
Method:
There are many preparation methods for MNPAA. One commonly used method is to add sodium nitrite to phenylacetic acid, and then undergo a methylation reaction. Specific reaction conditions will vary, generally need to pay attention to safety factors and reaction control.
Safety Information:
MNPAA is an organic compound that has an irritating effect on the skin, eyes and respiratory system, and may cause adverse reactions such as skin sensitivity, respiratory tract irritation and eye irritation. When using or handling MNPAA, wear appropriate respiratory protective equipment and chemical protective gloves, avoid contact with skin and eyes, and avoid breathing in its vapor or dust. In the case of accidental contact, rinse immediately with plenty of water and seek medical help.
Due to the explosive nature of MNPAA, it should be properly stored away from fire sources, high temperatures and oxidants. The MNPAA should be used and handled in a well-ventilated area and in accordance with the relevant safety practices.
