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.

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-3-iodo-4-methylpyridine features a halogenated pyridine core with distinct regiochemistry, enabling selective cross-coupling reactions in late-stage functionalization. The methyl group enhances solubility and modulates electronic properties, while the orthogonal bromo- and iodo-substituents allow sequential Pd-catalyzed transformations. This compound serves as a key scaffold for diversification in medicinal chemistry and materials science applications.

Application

2-Bromo-3-iodo-4-methylpyridine serves as a versatile building block for palladium-catalyzed cross-coupling reactions, enabling efficient access to substituted pyridine scaffolds. The orthogonal halogen reactivity—bromine undergoing Suzuki-Miyaura or Stille coupling, while iodine facilitates Negishi or Sonogashira transformations—allows sequential functionalization. Bench-stable and readily purified by column chromatography, it functions reliably in the synthesis of pharmaceutical intermediates and agrochemical candidates requiring regioselective diversification.
