What is Monostearin

Product name:Monostearin
CAS
: 123-94-4
Molecular Formula: C21H42O4
Molecular Weight: 358.56
Product description:White or yellowish waxy solid, has a pleasant smell, the smell of fat. Soluble in hot organic solvents, such as ether, benzene, acetone and mineral oil, insoluble in water. But in the presence of a small amount of surfactant, can be dispersed in water. Median lethal dose (200 mg/kg mice, the abdominal cavity). Goods are often single palmitic acid glycerol monostearate and glycerol ester mixture. Monoglycerides is water-in-oil type emulsifier, sharp shock hitches in hot water and emulsification. Molecular distilled monoglycerides than crude ester with high purity, color white, emulsification effect is good. The emulsification and preservation effect of more than two times the coarse monoglycerides, bread amylose composite index can be from a coarse monoglycerides 28 92.As emulsifier and surfactant in food or in cosmetics, plastic products inside and outside the lubricant.

Amprolium hydrochloride price

Product name:Amprolium hydrochloride
CAS
: 137-88-2
Molecular Formula: C14H20Cl2N4
Molecular Weight: 315.24
Product description:White or kind of white powder, odourless or almost odourless. Soluble in water, methanol and ethanol, slightly soluble in ether, insoluble in chloroform. Aqueous solution (1 + 10) PH 2.5 3.0. Mixed in the feed, especially under the condition of neutral slow decomposition, decomposition of heated to 248-249 ℃.Due to ammonia c Lin structure similar to thiamine, can produce competitive antagonism effect, if the ammonia c Lin drug concentration is too high, can cause chicks thiamine deficiency to perform multiple neuritis, increase feed thiamine is can make the chicken group rehabilitation, but significantly affect the activity of ammonia c Lin ball insect resistance. It is alleged that feed thiamine content in more than 10 mg per kilogram, ball insect resistant effect of chloropropanol moiety is starting to wane.

What is Phenolphthalein

Product name:Phenolphthalein
CAS
: 77-09-8
Molecular Formula: C20H14O4
Molecular Weight: 318.32
Product description:Belongs to crystal powder, almost insoluble in water. Its characteristic is in acidic and neutral solution is colorless, amaranth in alkaline solution.Phenolphthalein is a kind of weak organic acid, in the pH < 8.2 solution is colorless lactone type structure, when the pH > 8.2 for red quinoid structure.Phenolphthalein is white or yellow microstrip tiny crystals, soluble in water and soluble in alcohol. So often the mixture alcohol solution using phenolphthalein. When the phenolphthalein reagent drip into the water or neutral and acidic aqueous solution, there will be a white haze, this is because alcohol can miscibility with water by arbitrary proportion, poorly soluble in water in the reagent phenolphthalein exhalation.
