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.
