Potassium 4-Hydroxy-3-methoxybenzenesulfonate Hemihydrate is the hemihydrate of potassium guaiacolsulfonate. Guaiacolsulfonic acid, commonly used in the form of potassium guaiacolsulfonate. Guaiacolsulfonic acid is used as an expectorant for relieving symptoms of cough and mucus in the chest due to respiratory infections, asthma, colds, or hay fever. Guaiacolsulfonate works by thinning mucus (phlegm) in the lungs and making it less sticky and easier to cough up. 'is reduces chest congestion by making coughs more productive.
