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

4,6-Dichloro-2-methylpyrimidine-5-carbaldehyde features a reactive aldehyde group flanked by electron-withdrawing chlorine atoms and a methyl substituent, enabling selective coupling in heterocyclic synthesis. This bench-stable scaffold integrates readily into pharmaceutical intermediates and functional materials, offering high compatibility with nucleophilic addition and condensation reactions under standard conditions.

Application

4,6-Dichloro-2-methylpyrimidine-5-carbaldehyde serves as a versatile building block in heterocyclic synthesis, enabling efficient construction of pyrimidine-based scaffolds. Its dual electrophilic sites—chlorine atoms at C4 and C6—facilitate selective substitution, while the aldehyde group provides a handle for reductive amination, oxime formation, or coupling reactions. Bench-stable and compatible with standard reaction conditions, it functions effectively in medicinal chemistry campaigns requiring functionalized pyrimidines.
