Introduction	D-panthenol (D-panthenol) is an active compound of D-pantothenic acid and a precursor of coenzyme A, it is an important vitamin drug, which can be converted into pantothenic acid and then synthesized into coenzyme A. It promotes the metabolism of human protein, fat and carbohydrate, protects the mucous membrane and luster of skin surface, and prevents the occurrence of diseases, D-panthenol as a nutritional supplement, widely used in medicine, food, cosmetics industry, specific preparations such as Oral Liquid, eye drops, multi-vitamin injection, shampoo, mousse, skin cream, etc.
properties	is a colorless to yellowish transparent viscous liquid that may crystallize during long-term low-temperature storage. There is a slight special odor, easy to absorb moisture. D-panthenol soluble in water, methanol, ethanol, insoluble in ether, chloroform, oil and fat. It is relatively stable in air and light.
Application	dexpanthenol (D-panthenol) is an active compound of D-pantothenic acid and a precursor of coenzyme A, it is an important vitamin drug, which can be converted into pantothenic acid and then synthesized into coenzyme A. It promotes the metabolism of human protein, fat and carbohydrate, protects the mucous membrane and luster of skin surface, and prevents the occurrence of diseases, D-panthenol as a nutritional supplement, widely used in medicine, food, cosmetics industry, specific preparations such as Oral Liquid, eye drops, multi-vitamin injection, shampoo, mousse, skin cream, etc.
range of use	is widely used in the pharmaceutical, food, and cosmetic industries. In the pharmaceutical industry, as a vitamin B drug, involved in metabolism; In the food industry, used as a nutritional supplement and fortifier, promote the metabolism of human protein, fat, carbohydrate, maintain the skin and mucous membranes, improve hair gloss, improve immunity, prevent the occurrence of diseases; In the cosmetics industry: the role of care on the skin is manifested in the deep penetration of moisturizers, stimulate the growth of epithelial cells, promote wound healing, anti-inflammatory effect; The role of care on the hair is manifested in a lasting moisturizing function, prevent split hair, damage, increase the density of the hair, improve the luster of the hair; the nursing of the nail is manifested by improving the hydration of the nail and imparting flexibility to the nail.
identification test	in 1 Ml of 10% sample solution, add sodium hydroxide solution (TS-224)5Ml and copper sulfate solution (TS-78) drops, vigorous shaking. Should present dark blue. 1 ml of 1mol/L hydrochloric acid was added to 1 ml of 1% aqueous sample solution, and the mixture was heated on a steam bath for about 30min. After cooling, 100mg of hydroxylamine hydrochloride was added and mixed well, and 5ml of sodium hydroxide solution (TS-224) was added. After standing for 5min, the pH value was adjusted to 2.5-3.0 with 1mol/L hydrochloric acid, and 1 drop of ferric chloride test solution (TS-101) was added. Should appear reddish purple.
content analysis	accurately weigh a sample of about 400mg and place it in a reflux flask with a standard port, add 50.0mL 0.1mol/L perchloric acid in glacial acetic acid solution and reflux for 5H. After cooling, the condenser was covered with a metal foil to prevent water contamination, and the condenser was rinsed with glacial acetic acid. Add 5 drops of crystal violet test solution (TSl74), then use 0.1mol/L potassium hydrogen phthalate glacial acetic acid solution titration to Blue Green end point. At the same time, the blank test was carried out and the necessary correction was made. Perchloric acid is equivalent to 20.53mg of panthenol (C9H1 9NO4) per mL of 0.1mol/L.
toxicity	GRAS(FDA,§ 182.5580,2000).
Use	for hair care, skin moisturizers, and helps skin wound healing, fight inflammation, It is widely used as pharmaceutical intermediates in medicine, food, cosmetics and liquid preparations . is a precursor of vitamin B5.
production method	1. D-pantolactone and 3-aminopropanol were mixed in methanol and condensed. The reaction was as follows:
