Known Application

2-Ethoxyethyl 4-methylbenzenesulfonate is an important intermediate in the synthesis of Bilastine, an antihistamine used for treating allergic rhinitis and urticaria. During the synthesis of complex molecules like Bilastine, certain functional groups need to be temporarily protected to prevent them from reacting prematurely or undesirably. 2-Ethoxyethyl 4-methylbenzenesulfonate can act as a protecting group for hydroxyl or amino groups, allowing chemists to selectively modify other parts of the molecule. 2-ethoxyethyl 4-methylbenzenesulfonate can enhance the overall yield and purity of the final product. 2-ethoxyethyl 4-methylbenzenesulfonate is crucial in the synthesis of Bilastine as it acts as both a protecting group and a leaving group, ensuring the correct assembly and high purity of the final pharmaceutical product.
