    HazMat Fee

    An item is classified as a dangerous good if our website displays Hazardous Material (HazMat) information for it. There is a HazMat shipping fee for each item that qualifies as a dangerous good, except in the following scenarios:

    The shipment is processed through FedEx Ground under the Limited Quantity option.

    Each bottle is packed as an Excepted Quantity, with a maximum of 1g for items in class 6.1 packing group I or II, and up to 25g for all other hazardous materials.

    If shipping is charged to your FedEx account, the HazMat fee will be billed directly by the courier. Otherwise, the fee will be included on your invoice. To help you avoid the HazMat fee, we can package a 5g order of a class 6.1 packing group I or II material as five separate 1g units, and a 100g order of any other dangerous good as four 25g units. This packaging adjustment will be made unless you instruct otherwise on your purchase order. Below, you will find the fee schedule from FedEx for handling hazardous materials.

Description

This 20% ethanol solution of 3-butyl-1-methyl-1H-imidazol-3-ium hydroxide delivers a stable, moisture-tolerant basic reagent with enhanced solubility in polar organic media. The imidazolium cation features a sterically hindered alkyl substitution pattern that resists degradation under standard bench conditions. Ideal for catalytic deprotonations and base-mediated transformations in synthetic workflows.

Application

3-Butyl-1-methyl-1H-imidazol-3-ium hydroxide, 20% in ethanol solution serves as a stable, bench-ready nucleophilic base for imidazolium salt functionalization and heterocycle synthesis. Its moderate basicity enables efficient deprotonation in polar aprotic environments, facilitating C–C bond formation and enabling clean reaction profiles with high functional group tolerance. The ethanol-based formulation enhances solubility and simplifies purification in synthetic workflows.
