Sodium dehydroacetate CAS#4418-26-2
Sodium dehydroacetate appears as a white or pale yellow substance—odorless and tasteless—with good solubility in water yet poor dissolvability in organic solvents like ethanol. It has a melting point of 190°C and exhibits excellent resistance to light and heat; its solution remains stable even after being heated at 120°C for 2 hours.In terms of its physical form and quality, the product is processed into a powder via spray drying, boasting high purity (≥98%), stable and reliable performance, as well as a low moisture content (≤2.6%). Additionally, its aqueous solution is neutral or slightly alkaline.
