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

Himic anhydride delivers a robust, electron-deficient platform for conjugate additions and cycloadditions. This bench-stable reagent features a strained cyclic structure that enhances reactivity toward nucleophiles while maintaining compatibility with diverse functional groups under standard conditions.

Application

Himic anhydride serves as a robust, bench-stable acylating agent for the selective modification of alcohols and amines under mild conditions. Its cyclic structure enables efficient formation of esters and amides with high functional group tolerance, facilitating streamlined synthesis in complex molecule construction. Widely used in peptide coupling and natural product derivatization, it offers predictable reactivity and clean byproduct removal, making it a reliable choice for scalable laboratory workflows.
