3-Nitrobenzyl alcohol

3-nitrobenzyl alcohol

3-Nitrobenzyl alcohol is an organic compound with the chemical formula C₇H₇NO₃. It is a nitro derivative of benzyl alcohol, where one of the hydrogen atoms on the benzene ring is replaced by a nitro group (-NO₂). This compound is a solid at room temperature and is used in various chemical synthesis processes, particularly in the production of pharmaceuticals and dyes.

Properties

3-Nitrobenzyl alcohol has a molecular weight of 153.13 g/mol. It is characterized by its pale yellow color and crystalline form. The compound is soluble in common organic solvents such as ethanol, diethyl ether, and chloroform, but it is relatively insoluble in water. Its melting point ranges from 78 to 82°C, making it solid at room temperature.

Synthesis

The synthesis of 3-Nitrobenzyl alcohol typically involves the nitration of benzyl alcohol using nitric acid. This process involves the substitution of a hydrogen atom on the benzene ring with a nitro group. The reaction requires careful control of temperature and the concentration of nitric acid to ensure the formation of the desired nitro compound without over-nitration or degradation of the benzyl alcohol.

Applications

3-Nitrobenzyl alcohol is primarily used as an intermediate in the synthesis of other chemical compounds. Its ability to undergo further chemical reactions makes it valuable in the production of pharmaceuticals, where it can be transformed into various active pharmaceutical ingredients (APIs). Additionally, it is used in the synthesis of dyes and pigments, where its properties contribute to the development of colorants with specific characteristics.

Safety

Handling of 3-Nitrobenzyl alcohol requires caution due to its potential health hazards. It can cause irritation to the skin, eyes, and respiratory system upon exposure. Therefore, appropriate safety measures, including the use of personal protective equipment (PPE) such as gloves and goggles, are recommended when working with this compound. Proper ventilation and handling procedures should be followed to minimize exposure and reduce the risk of health effects.
