Ramai molekul sasaran biologi atau prekursor sintetik mereka terdiri daripada rantai alkil dengan kumpulan fungsi tertentu dalam suatu urutan tertentu. Penggabungan terpilih, atau menambah bahagian ke rantai dengan kumpulan fungsi yang dikehendaki, digunakan, terutamanya jika tidak ada pendahulunya biologi biasa. Alkilasi dengan hanya satu karbon dipanggil metilasi. Dalam konteks penapisan minyak, alkilasi merujuk kepada alkilasi tertentu isobutane dengan olefin.
