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

(2-Chlorobenzoyl)hydrazine features a chlorinated benzoyl group linked to hydrazine, enabling direct integration into heterocyclic synthesis. This bench-stable reagent facilitates the construction of bioactive pyrazole and triazole frameworks under standard conditions. The ortho-chloro substituent enhances electrophilicity and directs regioselective cyclization.

Application

(2-Chlorobenzoyl)hydrazine serves as a versatile building block in heterocyclic synthesis, enabling efficient access to pyrazole and triazole scaffolds via cyclization reactions. Its ortho-chloro substituent enhances electrophilic reactivity while maintaining bench stability and compatibility with common functional groups. The hydrazide moiety facilitates coupling and condensation processes, making it well-suited for medicinal chemistry campaigns requiring modular scaffold construction.
