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 bench-stable hydrazine derivative features a sterically hindered aryl group that enhances reactivity control in coupling processes. The para-methyl substitution pattern increases electron density at the hydrazine nitrogen, facilitating selective imine formation and enabling efficient integration into complex heterocyclic scaffolds under mild conditions.

Application

(2,3-Dimethylphenyl)hydrazine hydrochloride serves as a reliable building block for heterocyclic synthesis, particularly in the construction of pyrazoles and other nitrogen-containing scaffolds. Its stability under standard bench conditions and compatibility with diverse coupling reactions enable efficient access to biologically relevant frameworks. The hydrazine functionality facilitates condensation with carbonyl compounds, offering a practical route to substituted heterocycles used in medicinal chemistry and agrochemical research.
