Abstract Sugarderivatives carrying various photolabile groups at various positions have been synthesised, namely, 4-azido-4-deoxy- d -galactose, 4-azi-4-deoxy- d -xylo-hexopyranose (4), 3,7-anhydro-2-azi-1,2-dideoxy- d -glycero- l -manno-octitol (6), and 3-azi-1-methoxybutyl β- d -glucopyranoside (8), and 4-(2-diazo-3,3,3-trifluoropropionyl)- d -glucose. They were tested for their applicability in

3-Azi-1-methoxybutyl beta-D-galactopyranoside, prepared from 2,3,4,6-tetra-O-acetyl-alpha-D-galactopyranosyl bromide in four steps, had an affinity constant for antigalactans IgA (Fab') J539 and X24 of 1550 and 1730 M-1, respectively. 3-Azi-1-methoxybutyl beta-D-(4-3H)galactopyranoside, when photolysed in the presence of IgA X24, specifically labelled the galactan-binding area of the immunoglobulin
