CAS 6117-80-2 — cis-2-Butene-1,4-diol

cis-2-Butene-1,4-diol is an unsaturated diol featuring a carbon-carbon double bond and two hydroxyl groups, primarily used as a building block in organic synthesis, polymer chemistry, and as a precursor for pharmaceutical intermediates. It serves in the production of specialty resins, adhesives, and as a cross-linking agent in polymer formulations. CAS 6117-80-2, a clear to pale yellow liquid with a mild odor, is non-hazardous (no signal word) and typically stored under inert conditions to prevent oxidation. Purity is generally ≥95% for research-grade applications. Molekula supplies cis-2-Butene-1,4-diol from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
