Crystalline hydrates of alkyl acyl acetaldehyde sulfites, preparation methods and uses thereof. The molecular formula of the hydrates of alkyl acyl acetaldehyde sulfites is CnH2n+1C(O)CH2CH(OH)SO3M·mH2O, wherein n=8-14, m=0.2-1.5, M is NH4+, Na+, K+, a pharmaceutically acceptable metal ion or an organic base. Compared with anhydrides of alkyl acyl acetaldehyde sulfites, the hydrates of alkyl acyl acetaldehyde sulfites have low hygroscopicity, therefore can be stored stably, and are convenient to transport and be formulated into preparations.
