CAS 5571-48-9 Magnesium dipropan-2-olate
Overview
Magnesium dipropan-2-olate (magnesium isopropoxide; CAS 556-61-6, Mg(OiPr)₂, ~142.4 g/mol) is a magnesium alkoxide reagent and Lewis-basic catalyst used across fine chemicals, pharmaceuticals, polymer synthesis, and materials R&D. It promotes transesterification, alcoholysis, and base-assisted condensation/enolate chemistry, and is frequently applied as an initiator/catalyst for ring-opening polymerization of lactones/lactide and as a clean Mg precursor for sol-gel and oxide film preparation. Supplied as a free-flowing solid or isopropanol solutions (custom strengths available), each lot can be delivered with low moisture/carbonate and full COA/TDS.
Product Description
CAS 5571-48-9 Magnesium dipropan-2-olate
Magnesium dipropan-2-olate (magnesium isopropoxide, Mg(OiPr)₂) is a versatile magnesium alkoxide catalyst used in organic synthesis, biodegradable polymer production, pharmaceuticals, and materials engineering. As a Lewis-acidic alkoxide and mild base, it efficiently promotes transesterification, alcoholysis, and condensation/enolate chemistry, and initiates ring-opening polymerization of lactide/lactones to deliver controlled molecular weight and low color.
