    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 molecular formula C12H24O6 and molar mass about 264.32 g/mol, with melting point commonly around 37-40 C and boiling point about 395.8 C at 760 mmHg. It is soluble in water and polar organic solvents and can soften near room temperature.
