    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

Tetraethylene glycol monomethyl ether offers exceptional solubility in both polar and nonpolar media, enabling seamless integration into diverse synthetic workflows. This bench-stable, moisture-tolerant solvent features a linear polyether backbone that enhances compatibility with sensitive reagents. Its low volatility and high thermal stability streamline purification processes, making it ideal for reactions requiring gentle handling and extended reaction times.

Application

Tetraethylene glycol monomethyl ether serves as a versatile, bench-stable solvent and protecting group handle in synthetic organic chemistry. It facilitates solubilization of polar intermediates, enables efficient nucleophilic substitutions, and functions as a reliable linker in combinatorial libraries and polymer-supported syntheses. Its high functional group tolerance and ease of purification make it well-suited for multi-step transformations and scale-up applications.
