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+
Inaccessible (Haz class 6.1 or 9), International	$108.00+

Description

Naphthalen-1-ylhydrazine hydrochloride serves as a reactive hydrazine derivative for constructing hydrazone-linked architectures. This bench-stable compound integrates readily into synthetic routes requiring nitrogen-rich intermediates, offering reliable coupling under standard conditions.

Application

Naphthalen-1-ylhydrazine hydrochloride serves as a reliable building block for the synthesis of heterocyclic systems, particularly in the construction of quinazoline and pyrazole scaffolds. Its well-documented reactivity enables efficient condensation with carbonyl compounds under mild conditions, offering high yields and excellent functional group tolerance. The hydrochloride salt enhances bench stability and simplifies handling, facilitating purification and integration into multi-step synthetic sequences common in medicinal chemistry and process development workflows.
