Fursultiamine (CAS 804-30-8) is a synthetic lipophilic vitamin B1 derivative that appears as a white to off-white solid, whose tetrahydrofurfuryl disulfide structure gives it greater lipid solubility than thiamine hydrochloride, and it is used in thiamine-deficiency formulations, high-bioavailability supplements and fortified foods. Vitamin B1 carries authorised EU health claims (Reg. 432/2012) for normal energy-yielding metabolism, nervous system, cardiac, and psychological function.
