A new organic reagent, 1-isonicotynyl-2-furfurylidene hydrazine synthesized from isonicotinic acid hydrazid and furfural, gives yellow liquid with cadmium (II). Cadmium complex of the reagent is soluble in water with yellow coloratiop. The complex has a maximum absorption at 363mmc and molar ratio of cadmium to reagent was estimated as 1 : 1 by continuous variation method and slope method. Molecular extinction coefficient and apparent formation constant of this complex was spectrophotometrically determined. K=4.48 X 103 (Babko''s method) K=1.33 X 103 (Anderson''s method)
