Bisphenol A (CAS 80-05-7) is 4,4'-isopropylidenediphenol, a diphenol. Its largest use is the manufacture of polycarbonate, followed by epoxy resins (reacted with epichlorohydrin); it is also used in unsaturated polyester, polysulfone, and polyetherimide resins and as a chemical intermediate. It also serves as a monomer and antioxidant in certain plastics.

Regulatory restriction status
Bisphenol A (BPA) (CAS 80-05-7) appears on the regulatory list(s) below. This is public regulatory information about the substance — not a statement about any specific supplier’s material, and not a safety claim. Confirm the current status for your jurisdiction and intended use.
- California Proposition 65: listed for reproductive toxicity, listed 11 May 2015. A California Proposition 65 warning applies (see the warning above).
- REACH Restriction (Annex XVII), entry 66: specific EU uses/conditions of the substance are restricted.
- REACH SVHC Candidate List (EU): listed 12 Jan 2017 on the basis of toxic for reproduction (Art. 57(c)), endocrine-disrupting properties (Art. 57(f)). SVHC status triggers EU supplier-communication and notification duties above 0.1% w/w; it is not, by itself, a ban on sale.

Frequently Asked Questions
What is bisphenol A (BPA) used for?
Bisphenol A (CAS 80-05-7) is 4,4'-isopropylidenediphenol, a diphenol. Its largest use is polycarbonate manufacture, followed by epoxy resins (reacted with epichlorohydrin); it is also a building block for polysulfone, polyetherimide, and unsaturated polyester resins and serves as a chemical intermediate and antioxidant in select plastics.
What is the chemical formula and structure of bisphenol A?
Bisphenol A is 4,4'-isopropylidenediphenol (diphenylolpropane), molecular formula C15H16O2, CAS 80-05-7. It consists of two phenol rings joined by an isopropylidene bridge, which is why each ring's hydroxyl makes it a difunctional monomer for polycarbonate and epoxy chemistry.
What is another name for bisphenol A?
Bisphenol A is also called 4,4'-isopropylidenediphenol, diphenylolpropane, and BPA. It is CAS 80-05-7, HS heading 2907.23.
What is the cost of bulk bisphenol A?
Bulk BPA pricing depends on volume, packaging, grade, and destination, so we quote per order rather than list a fixed price. Send your target volume and delivery location for a current bulk quote.
How is bulk bisphenol A packaged and can you provide a CoA and SDS?
We supply BPA in bulk industrial packaging for polycarbonate, epoxy, and engineering-resin producers, with packaging and MOQ confirmed per order. A Certificate of Analysis and Safety Data Sheet accompany shipment; request a bulk quote with your target volume.
What is the REACH and TSCA regulatory status of Bisphenol A (BPA)?
Bisphenol A (BPA) (CAS 80-05-7) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 201-245-8).
