    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

Methylene diacetate serves as a versatile acetylating agent in organic synthesis, offering controlled reactivity under mild conditions. This stable, moisture-tolerant reagent facilitates efficient acetylation of alcohols and amines, enabling streamlined access to protected intermediates. Its compatibility with diverse functional groups supports applications in pharmaceutical process development and fine chemical manufacturing.

Application

Methylene diacetate serves as a stable, bench-friendly acetyl transfer agent enabling efficient acetylation of alcohols, amines, and thiols under mild conditions. Its high functional group tolerance and ease of handling make it a practical alternative to acetic anhydride in complex molecule synthesis.
