Butyl 4-aminobenzoate, cataloged under CAS number 94-25-7, is a fascinating molecule whose chemical structure dictates its wide-ranging utility. NINGBO INNO PHARMCHEM CO.,LTD. is deeply involved in understanding and optimizing the synthesis of this compound, recognizing its importance as both a pharmaceutical ingredient and a chemical intermediate.

The molecular formula for Butyl 4-aminobenzoate is C11H15NO2, with a molecular weight of 193.24 g/mol. Structurally, it features a para-aminobenzoic acid (PABA) core esterified with a butyl alcohol chain. This ester linkage is key to its properties, including its solubility and its anesthetic capabilities. The presence of the amine group also makes it reactive and suitable for further chemical modifications, which is crucial for its role in butyl 4-aminobenzoate synthesis of other compounds.

The synthesis of Butyl 4-aminobenzoate typically involves the esterification of 4-aminobenzoic acid with n-butanol. This reaction is often catalyzed by an acid, such as sulfuric acid or p-toluenesulfonic acid, to promote the formation of the ester bond. Alternatively, one can utilize the reaction of 4-aminobenzoyl chloride with n-butanol. The specific butyl 4-aminobenzoate synthesis route chosen by manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. depends on factors such as desired purity, cost-effectiveness, and environmental considerations.

Post-synthesis, purification steps are critical to achieve the high purity (often >98%) required for its various applications. Techniques such as recrystallization are commonly employed to remove impurities and obtain the characteristic white crystalline powder form of Butyl 4-aminobenzoate. NINGBO INNO PHARMCHEM CO.,LTD. prioritizes these purification processes to guarantee the quality and reliability of their chemical intermediate offerings, ensuring that customers receive a product that meets their exact butyl 4-aminobenzoate properties requirements.
