==History==

While Michael Strem was a graduate student, he spent time in Dr. Irving Wender's laboratory learning to synthesize and use [[cobalt carbonyl]]. They discussed setting up a chemical company, which resulted in Strem Chemicals.{{Cite journal |date=November 2005 |title=Biographical Sketch |url=https://www.strem.com/uploads/resources/documents/chemiker22.pdf |journal=The Strem Chemiker |volume=XXII |issue=1}} Later, [[cobalt carbonyl]] became Strem Chemical's first commercial product.{{Cite web |title=About Strem |url=https://www.strem.com/about/ |access-date=2024-06-15 |website=www.strem.com}}

While a graduate student, Michael Strem worked in the laboratory of Irving Wender, where he gained experience synthesizing and handling [[Dicobalt octacarbonyl|cobalt carbonyl]]. During this period, the two discussed establishing a chemical company to supply high‑purity coordination and organometallic compounds, which ultimately led to the founding of Strem Chemicals in 1964.{{Cite journal |date=November 2005 |title=Biographical Sketch |journal=The Strem Chemiker |volume=XXII |issue=1}}

Strem Chemicals manufactures and markets [[specialty chemicals]] of high purity, provides custom synthesis and [[Current Good Manufacturing Practices|cGMP]] manufacturing services, and supplies about 4,500 specialty products in the area of metals, [[Inorganic compound|inorganics]], [[organometallic]]s and [[nanomaterials]].

Cobalt carbonyl later became the company’s first commercial product, manufactured using high‑pressure autoclave technology. Over time, Strem expanded its catalog beyond early metal carbonyls to include a wider range of inorganic and organometallic reagents supporting synthetic chemistry and materials research.Craig Bettenhausen, ''Chemical & Engineering News'', April 8, 2021.

Strem Chemicals supports the [[American Chemical Society]] Award for Distinguished Service in the Advancement of Inorganic Chemistry and the [[Canadian Society for Chemistry]] Award for Pure or Applied Chemistry.{{Cite web |date=2009 |title=Strem Chemicals Supports Innovation |url=https://www.strem.com/uploads/news/documents/stremsponsorsinnovation_awards.pdf |access-date=2024-06-14 |website=Strem Chemicals}}
