Covestro's Makrolon polycarbonate, invented by Bayer in 1953, is used in automotive glazing, electronics housings, and medical devices. The material's impact resistance and optical clarity made it indispensable.

Reaxys is built on the Beilstein Handbook of Organic Chemistry (began 1881) and Gmelin inorganic database. It provides reaction pathways, physical properties, and bioactivity data for millions of compounds — essential for synthesis planning.

The Solvay process, patented in 1861, converts salt and limestone to sodium carbonate (soda ash) using ammonia. This replaced the Leblanc process and became the dominant method for making soda ash for glass, soap, and paper industries.
