Products Description of Guaifenesin CAS#93-14-1
Guaifenesin, also known as methyl glyceryl benzene diether, guaifenesin, guaifenesin glycerol ether, and glyceryl guaifenesin, is a stimulating expectorant. After oral administration, it can stimulate the gastric mucosa, reflexively cause increased secretion of bronchial mucosal glands, reduce the viscosity of sputum, and make sticky sputum easier to cough up. It is suitable for treating people with a lot of sputum that is difficult to cough up. Guaifenesin has a disinfecting and preservative effect, can reduce the stench of sputum, and also has antitussive, antispasmodic, and anticonvulsant effects. It is used for cough with sputum, lung abscess, bronchiectasis, and secondary asthma in chronic bronchitis, and is often used in combination with other antitussive and antiasthmatic drugs. It can be absorbed from the gastrointestinal tract and reaches a peak blood concentration after 1 to 3 hours. Most of it is excreted from the intestines, and a small amount is metabolized to glucuronic acid conjugates and quickly excreted in the urine.
White crystalline powder. Melting point 78.5-79℃, boiling point 215℃ (2.53kPa). At 25℃, 1g of the product can be dissolved in 20ml of water, soluble in ethanol, chloroform, glycerol, dimethylformamide, easily soluble in benzene, insoluble in petroleum ether. Slightly bitter, with a slightly special smell.
