Our first Strem Catalog was published in 1965. The catalog was focused mainly on metal carbonyl products and their derivatives, organometallics as well as other organic chemicals and included a bisphosphine ligand and metal catalyst. Some of the products in our first catalog are still made at Strem today, such as cobalt carbonyl (27-0400), chromium carbonyl (24-0183) and more... See the link below for the full Strem product line. Our commitment to quality has only improved with age!
