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

2,4-Dichloro-5,6-dimethylpyrimidine serves as a pivotal building block in heterocyclic synthesis, featuring two chlorine atoms at electron-deficient positions and methyl groups that enhance regioselectivity. This bench-stable scaffold integrates readily into pharmaceutical intermediates and agrochemical frameworks, offering predictable reactivity under standard conditions.

Application

2,4-Dichloro-5,6-dimethylpyrimidine serves as a versatile building block in medicinal chemistry and agrochemical synthesis. Its electron-deficient pyrimidine core enables nucleophilic substitution at C2 or C4 positions, facilitating the construction of diverse heterocyclic scaffolds. The methyl groups enhance metabolic stability and modulate electronic properties, while the dichloro substitution pattern provides orthogonal reactivity for sequential functionalization. This compound exhibits good bench stability and is compatible with standard coupling protocols, making it a practical choice for parallel synthesis campaigns and process development.
