A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Pentaerythritol (CAS 115-77-5) is a tetrahydric alcohol (tetraol) used as a high-functionality polyol. Industry references record its use in alkyd resins, rosin and tall-oil esters, radiation-cure monomers, synthetic lubricants, and antioxidant intermediates. Supplied as a bulk polyol intermediate.
Frequently Asked Questions
What is pentaerythritol used for?
Pentaerythritol (CAS 115-77-5) is a high-functionality tetraol used as a polyol intermediate. Its main industrial uses include alkyd resins and varnishes, rosin and tall-oil ester resins, radiation-cure acrylate monomers (e.g. PETA), synthetic ester lubricant base stocks, and hindered-phenol antioxidant intermediates.
Is pentaerythritol a polyol?
Yes. Pentaerythritol is a tetrahydric alcohol (tetraol), meaning it carries four hydroxyl groups, which makes it a high-functionality polyol valued for crosslinking and esterification chemistry.
Is pentaerythritol an alcohol?
Yes. It is a polyhydric alcohol with four primary hydroxyl groups (molecular formula C5H12O4). Those four reactive -OH sites are what make it useful as a backbone for esters, resins, and acrylate monomers.
What is the common name for pentaerythritol?
Pentaerythritol is its standard chemical name; it is also referred to by synonyms such as 2,2-bis(hydroxymethyl)-1,3-propanediol and the trivial name penta. It is supplied as a bulk crystalline polyol intermediate, distinct from its nitrate ester derivative.
What is the price of bulk pentaerythritol and how is it packaged?
RawSource supplies pentaerythritol as a bulk polyol intermediate in industrial packaging such as bags, drums, and larger volumes for manufacturers. Pricing is volume- and grade-dependent; request a bulk quote with your target quantity and ship-to, and we will include current CoA and SDS. It typically classifies under HS 2905.42.
