The present study reports on new solid forms obtained from thiamine hydrochloride with succinic acid by applying the liquid assisted grinding (LAG) mechanochemical method. Samples with (1:1) and (1:2) molar ratios of thiamine hydrochloride to succinic acid resulted after two hours grounding with few drops of acetonitrile were investigated by X-ray diffraction, thermal analysis and infrared spectroscopy. Both XRD and FTIR analysis show new diffraction lines and absorption bands, respectively, denoting that there is not simply a mechanical mixture of components. The FTIR results indicate that a new salt of thiamine hydrochloride with succinic acid was obtained owing to proton transfer..
