Specification
l-Camphor (CAS NO.464-48-2) is also named as Alcanfor ; (1s,4s)-(-)-Campho ; 7,7-Trimethyl-(1s)-bicyclo(2.2.1)heptan-2-on ; 7,7-Trimethyl-(1s)-bicyclo[2.2.1]heptan-2-on ; Camphor, (1s,4s)-(-)- ; Camphor, l-, (-)- ; Camphore ; Levo-(-)-camphor . l-Camphor (CAS NO.464-48-2) is white crystals with slightly bitter and cooling taste. Burns with a bright, smoky flame. It is flammable. It is slightly water soluble. l-Camphor may be sensitive to heat and direct sunlight. It is incompatible with strong oxidizing agents, strong reducing agents and chlorinated solvents. Also incompatible with potassium permanganate. Salts of any kind should not be added to l-Camphor in water. Reacts violently with chromic anhydride .
