4-Ethoxy-3-nitrobenzoic acid(CAS: 59719-77-6)

4-Ethoxy-3-nitrobenzoic acid (CAS: 59719-77-6) is a crystalline solid at room temperature with a molecular weight of approximately 222.18 g/mol. It has a high solubility in organic solvents like ethanol and acetone, but is only slightly soluble in water. This compound is moderately reactive, particularly towards nucleophilic substitution and reduction reactions. It has a pKa value of around 4, indicating it is a weak acid.

4-Ethoxy-3-nitrobenzoic acid can be synthesized by the nitration of 4-ethoxybenzoic acid followed by hydrolysis. Commonly, this involves reacting 4-ethoxybenzoic acid with a nitration mixture of concentrated sulfuric acid and fuming nitric acid. The reaction is typically carried out in an ice bath to control the temperature, and the yield can be up to 75%. This process requires strict monitoring to ensure selectivity and safety.

4-Ethoxy-3-nitrobenzoic acid (CAS: 59719-77-6) finds applications in the pharmaceutical industry, where it serves as a precursor for the synthesis of various medicinal compounds. It is also used in the production of organic sensors and in the synthesis of certain polymer materials. Additionally, it may be employed in the semiconductor industry for specific chemical processes.

When handling 4-Ethoxy-3-nitrobenzoic acid (CAS: 59719-77-6), safety goggles, laboratory coat, and gloves are essential. Work should be conducted in a well-ventilated area or a fume hood due to its potential volatility. Spills should be handled with appropriate absorbent materials and disposed of according to chemical waste protocols. Always consult the Safety Data Sheet (SDS) for detailed information on handling and disposal.
