Azithromycin has the chemical name (2R,3S,4R,5R,8R, 10R,11R,12S,13S,14R)- 13-[(2,6-dideoxy-3-C-methyl-3-O-methyl-?-L-ribo-hexopyranosyl) oxy]-2-ethyl-3,4,10-trihydroxy-3,5,6,8,10,12,14-heptamethyl-11-[[3,4,6-trideoxy-3- (dimethylamino)-?-D-xylo-hexopyranosyl]oxy]-1-oxa-6-azacyclopentadecan-15-one. Azithromycin is derived from erythromycin; however, it differs chemically from erythromycin in that a methyl-substituted nitrogen atom is incorporated into the lactone ring. Its molecular formula is C38H72N2O12, and its molecular weight is 749.00. Azithromycin, as the dihydrate, is a white crystalline powder with a molecular formula of C38H72N2O122H2O and a molecular weight of 785.0.
