Phenol Detached Crystals Extra Pure
$ 17.20
Phenol Detached Crystals Extra Pure is a high-purity form of phenol, presented as colorless to white crystalline solids with a distinct, sharp odor. Known chemically as hydroxybenzene, phenol is both a weak acid and an effective antiseptic, offering versatile utility across laboratory, pharmaceutical, and industrial settings.
This Extra Pure grade is ideal for analytical chemistry, microbiological applications, and organic synthesis, especially in the production of resins, dyes, and plasticizers. It is also used in limited concentrations in medical preparations for its disinfectant properties. Phenol is highly corrosive and toxic upon contact or inhalation, requiring strict adherence to safety precautions, including the use of gloves, goggles, and fume hoods. It should be stored in tightly closed, light-resistant containers in cool, dry areas away from oxidizing agents.
