    Product Description

    18-Crown-6, CAS 17455-13-9, is a macrocyclic polyether also known as 18-Crown-6 Ether and 1,4,7,10,13,16-Hexaoxacyclooctadecane. Its six ether oxygen atoms form a cavity that can coordinate potassium ions and other cations of a suitable size.

    It is used as a cation-complexing reagent and phase-transfer catalyst in organic synthesis, coordination chemistry and analytical applications. By complexing alkali-metal cations, it can improve the transfer or reactivity of associated anions in non-aqueous reaction systems. Suitability should be assessed against the target cation, solvent system and intended reaction.

    Commercial specifications may differ in assay, Karl Fischer water, appearance and melting range. Confirm the required grade, current specification, batch COA and SDS before use. For a quotation, provide the required assay and water limit, application, quantity, packaging and destination.

    FAQ - Technical & Supply Chain

    • Q:

      Is 18-Crown-6 interchangeable with other crown ethers?

      A: No. 18-Crown-6 is the macrocycle identified by CAS 17455-13-9 and formula C12H24O6. Other crown ethers have different cavity sizes and cation selectivity. State the exact crown ether, target cation, solvent system and required grade when requesting material.
    • Q:

      Which specifications should be checked for 18-Crown-6?

      A: Confirm assay by the stated method, water by Karl Fischer, appearance, melting range and identity. The material can soften near its melting range and take up moisture, so agree the storage temperature, moisture-barrier packaging, net quantity and batch analysis.
    • Q:

      What are typical applications of 18-Crown-6?

      A: 18-Crown-6 is used as a phase-transfer reagent, cation-complexing agent and intermediate in organic or coordination chemistry where its cavity is suitable for potassium and similarly sized cations. The required grade depends on whether it will be used in synthesis, analytical work or process chemistry.
    • Q:

      How should 18-Crown-6 be stored?

      A: Store in tightly closed, moisture-barrier packaging in a cool, dry, ventilated area. Avoid prolonged exposure to moisture and heat, and confirm the storage temperature if the product may soften near its melting range.
    • Q:

      What are the key physical properties of 18-Crown-6?

      A: 18-Crown-6 has the molecular formula C₁₂H₂₄O₆ and a molar mass of 264.32 g/mol. Commercial grades are typically supplied as crystals or a crystalline mass and commonly specify a melting range of about 36–45 °C. Because appearance can change near the melting range, confirm appearance, assay, melting range and Karl Fischer water against the current specification and batch COA.
