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

2-Bromo-5-chloropyrimidine serves as a key heterocyclic building block for medicinal chemistry and agrochemical synthesis. The molecule features two distinct halogen substituents at adjacent positions, enabling sequential cross-coupling reactions. This combination provides high reactivity in palladium-catalyzed transformations while maintaining stability under standard bench conditions.

Application

2-Bromo-5-chloropyrimidine serves as a versatile building block in heterocyclic synthesis, enabling palladium-catalyzed cross-coupling reactions and nucleophilic substitution processes. Its orthogonal halogen reactivity facilitates selective functionalization at either the 2- or 5-position, supporting the construction of complex pyrimidine-based scaffolds relevant to medicinal chemistry and agrochemical development. The compound exhibits good bench stability and is readily purified by recrystallization or flash chromatography.
