4-Nitrocinnamic acid(CAS: 619-89-6)

4-Nitrocinnamic acid (CAS: 619-89-6) is a white crystalline solid with a molecular weight of approximately 192.08 g/mol. It is sparingly soluble in water but soluble in common organic solvents like ethanol and acetone. Chemically, it is relatively stable but can react with strong bases to form the corresponding salt. It has a melting point of about 235-238°C.

4-Nitrocinnamic acid (CAS: 619-89-6) is typically synthesized by nitration of cinnamic acid in the presence of a catalyst like concentrated sulfuric acid. The nitration reaction is exothermic and should be performed in a well-ventilated environment with temperature control. The yield is around 75-80%, and the purity can be enhanced through recrystallization.

4-Nitrocinnamic acid (CAS: 619-89-6) finds applications in the pharmaceutical industry for the synthesis of certain intermediates and in the sensor industry for developing pH and acid-base indicators. It is also used in research for dye synthesis and in the preparation of metal complexes.

When handling 4-Nitrocinnamic acid (CAS: 619-89-6), wear appropriate personal protective equipment (PPE) such as gloves, safety goggles, and a lab coat. Ensure the work is conducted in a well-ventilated area or a fume hood. Handle with care to avoid skin contact and inhalation of dust. Spills should be cleaned up promptly using appropriate absorbents, and the material safety data sheet (MSDS) should be consulted for detailed safety information.
