I also face the same problem. I did dissolved in 0.5M HCL, it dissolved in the beginning. However when I aliquoted and froze them in -20C, it precipitates.

according to the merck index (9th edition), adenine is soluble to 1 gm in 2000 ml water, 40 ml boiling water; the hydrochloride hemihydrate is soluble to 1 gm in 42 ml water.
when you reduce the temperature it will become less soluble. it should redissolve when you warm it back to room temperature or above (it may require some vigorous mixing).
