Ionic Liquids — Ordering & Product FAQs

What purity grades do RoCo® ionic liquids come in?

RoCo® offers ionic liquids in standard grade (≥95%), high-purity grade (≥98–99%), and ultra-high-purity grade (≥99.9%) with full Certificate of Analysis (COA) and Safety Data Sheet (SDS) included with every order. Custom purity specifications are available through our synthesis services.

What is the minimum order quantity for ionic liquids?

RoCo® offers flexible ordering from research-scale quantities (as low as 5g or 25g) through bulk industrial volumes. Most catalog products are available in 25g, 100g, 500g, and 1kg packaging. Contact our team for custom volume pricing and lead times.

Which ionic liquid is best for battery electrolytes?

Pyrrolidinium and piperidinium-based ionic liquids paired with TFSI− or FSI− anions are widely preferred as battery electrolytes due to their wide electrochemical windows (up to 5–6V), high ionic conductivity, and excellent thermal stability. Browse our dedicated Battery Materials category or contact us for application-specific recommendations.

Do you ship ionic liquids internationally?

Yes. RoCo® ships throughout North America with U.S.-based logistics and warehousing. We also offer international shipping with full export compliance documentation and cross-border support. Contact us for international quotes and lead times.
