CAS 638-10-8 — Ethyl 3,3-dimethylacrylate

Ethyl 3,3-dimethylacrylate (CAS 638-10-8) is a branched-chain acrylic ester used primarily in polymer synthesis, coatings, and adhesives for its excellent film-forming properties and UV resistance. It serves as a comonomer in producing durable plastics, UV-curable resins, and specialty elastomers. This clear, colorless liquid has a mild odor and is classified as non-hazardous with no signal word under GHS. It boasts a purity of ≥98%, a boiling point of 144–147°C, and a density of ~0.88 g/cm³ at 25°C. Molekula supplies Ethyl 3,3-dimethylacrylate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
