Product overview
Phenol (hydroxybenzene, carbolic acid, CAS 108-95-2) is the simplest aromatic alcohol: a benzene ring carrying one hydroxyl group. At room temperature it is a colorless to white crystalline solid with a characteristic sweet, medicinal odor; it melts at 43 °C, boils at 181.9 °C and has a flash point of 72.5 °C. It is slightly soluble in cold water and miscible with ethanol, ether, chloroform and glycerol.
The grade offered is specified at ≥ 99.95 wt% phenol with ≤ 150 ppm total organic impurities, ≤ 100 ppm cresols, ≤ 500 ppm moisture, a crystallization point of ≥ 40.6 °C, molten color ≤ 20 Pt-Co, ≤ 0.005 wt% evaporation residue, ≤ 0.5 ppm iron and ≤ 10 ppm ignition residue. It is delivered as a clear molten liquid without precipitation or turbidity, or as crystalline solid.
Phenol is the starting point for bisphenol A (polycarbonate and epoxy resins), phenol-formaldehyde resins, caprolactam for nylon 6, alkylphenols, salicylic acid and many pharmaceutical intermediates. It is toxic and corrosive to skin and is transported as UN 2821. ChemPortal supplies it in drums or heated ISO tank containers.

Frequently asked questions
Is phenol supplied as a liquid or a solid?
Both. Bulk quantities travel molten at about 50–60 °C in heated ISO tank containers; smaller lots are supplied as crystalline solid in drums and are melted by the user in a hot-water or steam-jacketed room.
What does the crystallization point tell me?
It is a sensitive purity indicator: pure phenol crystallizes at about 40.9 °C and dissolved water or cresols lower the value. The ≥ 40.6 °C specification confirms the ≥ 99.95 wt% purity of this grade.
What are the handling hazards?
Phenol is toxic and causes severe chemical burns that may be painless at first; it is absorbed through the skin. Use full protective clothing, face protection and polyethylene glycol or copious water for first aid, as described in the SDS. Transport classification is UN 2821.
