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+

Description

2-Bromo-4-fluoro-5-methylpyridine features a strategically positioned bromine and fluorine substituent on a methylated pyridine core, enabling selective cross-coupling reactions. The electron-deficient ring facilitates palladium-catalyzed transformations, while the methyl group enhances solubility and steric profile. This compound serves as a key intermediate in medicinal chemistry for constructing bioactive heterocycles under standard conditions.

Application

2-Bromo-4-fluoro-5-methylpyridine serves as a versatile building block in medicinal chemistry, enabling late-stage functionalization via palladium-catalyzed cross-coupling reactions. Its orthogonal halogenation pattern facilitates selective derivatization at the bromo position while preserving the fluorine and methyl groups. The compound exhibits good bench stability and compatibility with standard reaction conditions, making it suitable for constructing diverse heterocyclic scaffolds and API intermediates.
