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

5-Bromo-2,4-dichloro-6-methylpyrimidine serves as a key heterocyclic scaffold for medicinal chemistry and agrochemical synthesis. The molecule features a sterically accessible pyrimidine core with strategically positioned halogens and a methyl group, enabling selective cross-coupling reactions under standard conditions. This combination facilitates efficient derivatization in late-stage functionalization workflows.

Application

5-Bromo-2,4-dichloro-6-methylpyrimidine serves as a versatile building block in heterocyclic synthesis, enabling efficient access to substituted pyrimidines via palladium-catalyzed cross-coupling and nucleophilic substitution reactions. Its orthogonal reactivity profile—bromine at C5 for coupling, chlorines at C2/C4 for selective displacement, and methyl group at C6 for derivatization—facilitates modular construction of pharmaceutical scaffolds. Bench-stable and readily purified by recrystallization, it supports scalable synthesis workflows in medicinal chemistry and process development.
