Guaifenesin nrog CAS 93-14-1 99% Purity Pham Qib
Hmoov dawb crystalline, melting point 78.5-79 ℃, boiling point 215 ℃ (2.53kPa). Ntawm 25 ℃ 1g ntawm cov khoom no tuaj yeem yaj rau hauv 20ml dej, soluble hauv ethanol, chloroform, glycerol, dimethylformamide, nrog rau yooj yim soluble hauv benzene, insoluble hauv petroleum ether. Me ntsis iab, me ntsis tshwj xeeb tsw. Guaiacin yog ib qho expectorant, tseem hu ua guaiane, methoxybendiether, guaiacin thiab glycerin guaiacin ester. Tom qab noj, nws tuaj yeem ua rau lub plab zom mov reflex thiab ua rau bronchial mucosa gland secretion nce, txo qhov viscosity ntawm cov hnoos qeev thiab ua rau cov hnoos qeev nplaum yooj yim hnoos tawm. Nws kuj muaj cov teebmeem antiseptic, tuaj yeem txo qhov tsw ntawm cov hnoos qeev, tab sis kuj muaj cov teebmeem antitussive, spasmodic, anticonvulsive, rau mob bronchitis ntev nrog phlegm hnoos, mob ntsws abscess, bronchiectasis thiab mob hawb pob theem ob, thiab feem ntau siv nrog lwm cov tshuaj antitussive thiab antiasthmatic.
