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

3-Bromo-4,5-dichloropyridine features a highly reactive pyridine core bearing bromo and two chloro substituents at strategic positions, enabling selective cross-coupling in late-stage functionalization. The electron-deficient ring facilitates palladium-catalyzed transformations, while the orthogonal halogen reactivity supports sequential derivatization. This scaffold serves as a key building block for bioactive heterocycles in medicinal chemistry and agrochemical development.

Application

3-Bromo-4,5-dichloropyridine serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient late-stage functionalization via Pd-catalyzed cross-coupling reactions. The bromo group facilitates selective coupling under standard conditions, while the flanking chlorides enhance electrophilicity and provide orthogonal reactivity for sequential transformations. Its bench-stable nature and compatibility with diverse reaction conditions make it a practical choice for constructing complex heterocyclic scaffolds in API development.
