CAS 920-39-8 — Isopropylmagnesium bromide, 3M solution in 2-MeTHF

Isopropylmagnesium bromide is a Grignard reagent, a highly reactive organomagnesium compound widely used in organic synthesis for carbon-carbon bond formation, such as in the preparation of alcohols, ketones, and other complex molecules. This product is supplied as a 3 molar solution in 2-methyltetrahydrofuran (2-MeTHF), a safer alternative to traditional diethyl ether solvents. The CAS number is 920-39-8, with the molecular formula (CH3)2CHMgBr and a molecular weight of 147.31. It must be stored at ambient conditions but handled with caution—marked with the signal word "Danger" due to its reactivity with moisture and air. Molekula supplies Isopropylmagnesium bromide, 3M solution in 2-MeTHF from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
