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.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+

Description

Ethyl 4-hydrazinylbenzoate hydrochloride features a hydrazino group enabling direct coupling in heterocycle synthesis. This bench-stable derivative delivers high reactivity under mild conditions, facilitating efficient access to substituted pyrazoles and related scaffolds. The hydrochloride salt enhances solubility and handling in aqueous or polar organic media.

Application

Ethyl 4-hydrazinylbenzoate hydrochloride serves as a versatile building block for the synthesis of hydrazine-containing heterocycles and pharmaceutical intermediates. Its hydrazino group enables reliable condensation reactions with carbonyl compounds, facilitating access to pyrazole and triazole derivatives under mild conditions. The hydrochloride salt enhances bench stability and simplifies handling, while the ethyl ester supports downstream transformations such as hydrolysis or coupling. Functions effectively in standard organic synthesis workflows requiring controlled hydrazine reactivity.
