CAS 920-46-7 — Methacryloyl chloride 97% (stabilised)

Methacryloyl chloride 97% (stabilised) is a reactive acyl chloride used primarily in organic synthesis to prepare methacrylates, adhesives, and specialty polymers. It serves as a key intermediate in the production of acrylic resins and coatings. It is also used to make hydrogel materials for contact lenses, for example by functionalising poly(vinylpyrrolidinone) for copolymerisation with 2-hydroxyethyl methacrylate. This chemical has a CAS number of 920-46-7, with the molecular formula CH2=C(CH3)COCl and a molecular weight of 104.53. It is stored at ambient conditions and carries a signal word of Danger. Molekula supplies Methacryloyl chloride 97% (stabilised) from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
