Oxykem

OxyChem is the commonly used name for Occidental Chemical Corporation, a large industrial chemical manufacturer rather than a life sciences, biotech, pharma, or healthcare company. The business produces commodity and specialty chemicals including chlor-alkali products, vinyls/PVC, chlorinated organics, and calcium chloride for industrial end markets. Its products support downstream applications that can include pharmaceuticals and healthcare manufacturing, but OxyChem itself is not a therapeutic developer and does not operate a biotech-style clinical pipeline. Historically it was Occidental Petroleum's chemical business, and it was acquired by Berkshire Hathaway in January 2026 for approximately $9.7 billion. For the requested name "Oxykem," the closest clear company match appears to be OxyChem, but this is not an exact name match.
