For professionals in chemical research, development, and manufacturing, a deep understanding of compound properties is crucial for successful application. 4-Cyanobenzoic Acid (CAS 619-65-8) is a fine chemical intermediate that offers a compelling combination of structural features and reactivity, making it highly sought after across multiple sectors. Its physical appearance is typically described as a white to yellow-beige crystalline powder, with a melting point in the range of 219-221 °C (with decomposition).

The chemical stability of 4-Cyanobenzoic Acid is noteworthy; it is stable under recommended storage conditions (dry, dark, and ventilated places, below +30°C). However, it is noted to be air-sensitive and incompatible with strong oxidizing agents, strong acids, and strong bases, necessitating careful handling and storage protocols. Its solubility in methanol and a water solubility of 1.2 g/L at 25°C further define its usage parameters.

The versatility of 4-Cyanobenzoic Acid is evident in its broad range of applications. In organic synthesis, it serves as a fundamental building block due to its dual carboxylic acid and nitrile functionalities. This allows for the creation of complex molecules used in the pharmaceutical industry as intermediates for APIs, in agrochemicals for developing pesticides, and in the dye industry. Beyond synthesis, its properties are leveraged in material science for creating advanced polymers and liquid crystals, and in analytical chemistry as a standard for chromatographic methods.
