18-crown-6
Wuhan Silworld Chemical Co., Ltd. offers 18-crown-6, a cyclic polyether with the molecular formula C12H24O6 and CAS number 17455-13-9. This crown ether is a white crystalline solid with a typical melting point of 39-41°C. It functions primarily as a phase transfer catalyst, facilitating reactions by selectively complexing potassium cations in organic synthesis and pharmaceutical manufacturing.
The compound's structure, featuring six oxygen atoms in an 18-membered ring, creates a cavity size well-matched to the potassium ion. This selectivity makes it invaluable for applications beyond catalysis, including use in ion-selective electrodes and as a template in certain polymerization reactions. Standard laboratory grades typically offer a purity of 98% or higher, which is essential for reproducible results in sensitive synthetic pathways.
Industrial and research buyers, including pharmaceutical companies, fine chemical producers, and academic laboratories, source 18-crown-6 for its critical role in enabling specific chemical transformations. The listing from Wuhan Silworld does not specify MOQ, pricing, or lead times, so these trade terms must be negotiated directly. The supplier's location in Wuhan, Hubei Province, places it within a major Chinese chemical manufacturing and logistics corridor.

Sourcing 18-crown-6 from Wuhan Silworld Chemical Co., Ltd. - China Import Guide
Prior to ordering 18-crown-6 from Wuhan Silworld Chemical, obtain the detailed Certificate of Analysis (CoA) for the specific batch. This document should confirm purity, melting point, and any trace metal analysis, which are critical for its performance as a catalyst. Also request the Safety Data Sheet (SDS) for compliance with your local chemical handling regulations.
Clarify all trade logistics directly with the supplier. Confirm the available Incoterms (e.g., FOB Wuhan), payment terms, and estimated lead time for production and shipping. As a hygroscopic chemical, ensure the packaging specifications are suitable for transit conditions to your destination, and discuss any required import permits for controlled chemicals in your country.
For quality verification, consider ordering a sample for initial testing. Evaluate the material's performance in your specific application, such as its catalytic efficiency in a model reaction. Establish a clear quality agreement with the supplier regarding specifications, batch consistency, and procedures for handling any non-conforming material.
