Dibenzo-18-crown-6
Dibenzo-18-crown-6 supplied by Wuhan Silworld Chemical Co., Ltd. is a specialised macrocyclic polyether with the molecular formula C20H24O6 and CAS number 14187‑32‑7. The product is presented with a high assay of 98 %, indicating a high proportion of the target crown ether in each batch. It appears as a white solid that is stable under typical laboratory conditions and is compatible with a broad range of organic solvents. The supplier highlights its use as a phase‑transfer catalyst in organic synthesis and pharmaceutical manufacturing.
In the wider chemicals market the compound is classed as a high‑purity crown ether, typically exhibiting a molecular weight of 408.48 g·mol‑1 and a melting point around 150 °C. Density is commonly about 1.11 g·cm‑3, and solubility is strong in solvents such as dichloromethane, acetonitrile and methanol, which supports its role in extraction and supramolecular chemistry. Appearance is usually a fine white powder or solid, and the material is stored in sealed containers to avoid moisture uptake. These typical values help users design reaction conditions and safety protocols.
Research laboratories, fine‑chemical producers and pharmaceutical formulators use Dibenzo-18-crown-6 for metal‑ion extraction, analytical separations and as a catalyst in complex organic syntheses. The supplier offers flexible order quantities and ships the material in packaging suited for bulk handling, often 5 kg sealed bags, under either FOB or CIF terms. Buyers are advised to request the relevant ISO and SGS certificates and to confirm lead‑time, payment method and any specific handling instructions before finalising a purchase.
