Physical Description	Solid with a slight odor[HSDB] Crystals[Avocado Research MSDS]Small white to yellowish crystals or crystalline powderslight characteristic odour reminescent of thiazole
Stability/Shelf Life	Stable under normal storage conditionsit is degraded in neutral and alkaline solutions (even at room temp)Mononitrate is less hygroscopic and hence is more stable than the hydrochloride /Mononitrate and hydrochloride salts/Stability is excellent in low pH fruit drinks, eg, losses in drinks are 6% after 12 mo at room tempStability in frozen drink concentrate is excellentFor more Stability/Shelf Life (Complete) data for Vitamin B1 (9 total), please visit the HSDB record page.

Other Experimental Properties	Monoclinic plates in rosette-like clusters. Slight thiazole odorbitter tastedecomposes at 248 °C. One gram dissolves in approximately 1 mL water, 18 mL glycerol, 100 mL 95% alcohol, 315 mL absolute alcoholmore soluble in methanol. Soluble in propylene glycol. Practically insoluble in ether, benzene, hexane, chloroform. pH of 1% wt/vol solution in water 3.13pH of 0.1% wt/vol solution in water 3.58. On exposure to air of average humidity, the vitamin absorbs an amount of water corresponding to nearly one mole, forming a hydrate.HYGROSCOPICNUT-LIKE ODOR /HYDROCHLORIDE/READILY SPLIT BY SULFITE INTO ITS PYRIMIDINE & THIAZOLE CONSTITUENTSCrystals. MP: 196-200 °C, decomposespractically nonhygroscopicpKa = 4.9. Solubility in water (g/100 mL): 2.7 (25 °C)approximately 30 (100 °C). pH of 2% aqueous solution 6.5 to 7.1, more stable than the hydrochloridesuitable for enrichment of flours and feeds, multivitamin preparations /Mononitrate/SMALL WHITE CRYSTALS OR CRYSTALLINE POWDER /HYDROCHLORIDE/Thiamine hydrochloride in the dry state is stable. Acidic solutions having a pH below 5.5 preferably from 5.0 to 3.5 are also relatively stable. Alkalies destroy it. It is precipitated from solution by several of the alkaloidal reagents such as mercuric chloride, iodine, picric acid, tannin, and Mayer's reagent. It is sensitive to both oxidizing and reducing agents. /Hydrochloride/
