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

5,6-Dichloro-4-pyrimidinamine features a pyrimidine core bearing two chlorine substituents at the 5 and 6 positions and an amino group at the 4 position. This electron-deficient heterocycle serves as a key scaffold for medicinal chemistry applications, enabling direct incorporation into kinase inhibitors and antiviral agents. The compound exhibits bench-stable handling characteristics and compatibility with standard coupling reactions under mild conditions.

Application

5,6-Dichloro-4-pyrimidinamine serves as a versatile building block for the synthesis of pyrimidine-based scaffolds in medicinal chemistry and agrochemical research. Its dual chloro substituents enable efficient nucleophilic substitution reactions, facilitating the introduction of diverse aryl, heteroaryl, and amino groups under mild conditions. The compound exhibits good bench stability and is readily purified by standard chromatographic methods, making it well-suited for use in multi-step synthetic sequences requiring functional group tolerance and predictable reactivity.
