For professionals in the chemical industry, a deep understanding of a compound's properties is essential for successful application and synthesis. 4-Ethylbenzoic Acid (CAS: 619-64-7) is a compound with well-defined characteristics that make it valuable in various chemical processes. NINGBO INNO PHARMCHEM CO.,LTD. provides this critical intermediate and is dedicated to sharing key insights into its chemical profile.

Chemical Structure and Properties of 4-Ethylbenzoic Acid

4-Ethylbenzoic Acid, with the chemical formula C9H10O2 and a molecular weight of 150.174, belongs to the benzoic acid family. It features a benzene ring substituted with a carboxyl group (-COOH) and an ethyl group (-CH2CH3) at the para position. This specific structure imparts several key properties:

• Acidity: As a carboxylic acid, it exhibits acidic properties with a pKa value typically around 4.2-4.4, allowing it to participate in acid-base reactions and esterification.
• Solubility: While not readily soluble in water, it demonstrates good solubility in common organic solvents such as benzene, toluene, and methanol, which is advantageous for many synthesis procedures.
• Reactivity: The carboxyl group is reactive, enabling esterification, amide formation, and reduction reactions, while the aromatic ring can undergo electrophilic substitution.
• Stability: Under recommended storage conditions (cool, dry, tightly closed containers), it maintains its chemical integrity, crucial for long-term use as an intermediate.

Key Specifications for Industrial Use

From a manufacturing perspective, precise specifications are non-negotiable. Our 4-Ethylbenzoic Acid is supplied with a guaranteed purity of ≥99.0%. This high assay, coupled with a low loss on drying (≤0.5%), ensures that chemical reactions proceed with high efficiency and minimal impurities in the final product. Its physical appearance as white crystals also aids in quality control and handling. These attributes are vital for its primary applications as a pesticide intermediate, particularly in the synthesis of Methoxyfenozide and Tebufenozide, as well as in the development of liquid crystal materials and carbon nanotubes.
