CAS 6831-82-9 Potassium isopropoxide liquid
Overview
Potassium Isopropoxide (potassium propan-2-olate, potassium isopropylate; CAS 6831-82-9, C₃H₇KO, ~98.19 g/mol) is a strong potassium alkoxide used across fine chemicals, pharmaceuticals, agro intermediates, polymers, and biodiesel processes. As a powerful base and versatile reagent, it promotes transesterification, Claisen/Dieckmann condensations, eliminations, and selective deprotonation/alkylation, enabling fast, clean route development under anhydrous conditions.
Product Description
CAS 6831-82-9 Potassium isopropoxide
Product Characteristics — Potassium Isopropoxide (Potassium isopropylate, CAS 6831-82-9)
Potassium isopropoxide is a versatile potassium alkoxide base used across organic synthesis, biodiesel (isopropyl ester) production, polymer modification, pharmaceuticals, and fine chemicals. As a strong base and efficient catalyst, it drives transesterification, Claisen/Dieckmann condensations, E2 eliminations, and selective deprotonation/alkylation with fast, clean kinetics. The K⁺ counter-ion offers distinctive solubility/phase-behavior benefits versus sodium analogs in certain media, aiding process optimization. Available as isopropanol solutions (e.g., ~18–20% w/w, other strengths on request) or low-carbonate solids, it delivers high basicity and good compatibility in IPA systems—scaling from lab to continuous production. Highly moisture/CO₂-sensitive (and flammable in solution): store/handle under dry, inert conditions per SDS.
