Calcium content(Ca) % 8.2-8.6 Nitrogen content (N) % 5.7-6.0 Specific rotation[a] Dt +24--+28.5 Heavy metal (counting Pb) % ≤0.002 Loss in weight on drying % ≤5.0 Properties: White powder, no smell, light bitter, moisture absorption. The water solution is neutral or weakly alkaline. It is easy to solve in water, difficult in ethanol, almost not in chloroform or aether. Now we mainly produce D-calcium pantothenate, Vitamin K3 (MSB and MNB), garlic oil(100%), garlicin 10%, β-Alanine, L-pantolactone, Nicotinic Acid, Niacinamide, and β-Methylnaphthoquinone.
