    • PROBLEM TO BE SOLVED: To provide a composition containing 9-[2-[[bis[(pivaloyloxy)-methoxy]phosphinyl]methoxy]ethyl]adenine (adefovir dipivoxil; hereinafter referred to as AD) in a new form, having desirable properties for large-scale synthesis or for its formulation into therapeutic administration, to provide the AD having a good melting point, and/or a fluidity characteristic, or a bulk density characteristic for making it easy to produce the composition containing the AD and to formulate the composition, having a form fit to be stably stored, and capable of being rapidly filtered and easily dried, to provide the high-purity AD having a purity of at least about 97 (w/w)%, and preferably, having a purity of at least about 98 (w/w)%, and to provide a method for purifying the AD, capable of removing or minimizing a by-product produced during the synthesis of the AD, without using gas chromatography which is expensive and consumes time. SOLUTION: This crystalline AD has forms as follows: an anhydrous crystal form; a hydrate-type form; a methanol solvate-type form; a fumaric acid salt thereof; and a complex thereof.
