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

tert-Butyl (3,6-dichloropyridazin-4-yl)carbamate serves as a key synthetic intermediate featuring a dichlorinated pyridazine core. The tert-butyl carbamate group provides enhanced stability and ease of handling, enabling efficient incorporation into diverse molecular architectures. This compound facilitates the introduction of electron-deficient heterocyclic motifs in medicinal chemistry campaigns.

Application

tert-Butyl (3,6-dichloropyridazin-4-yl)carbamate serves as a versatile building block in medicinal chemistry, enabling selective functionalization at the pyridazine core. The carbamate group provides bench stability and facilitates deprotection under mild acidic conditions, while the 3,6-dichloro substitution pattern supports sequential cross-coupling reactions. Its compatibility with Pd-catalyzed transformations and tolerance to diverse functional groups make it ideal for constructing complex heterocyclic scaffolds in API development.
