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-Chloro-5-nitropyrimidin-4-amine features a dual-functional pyrimidine core bearing a chlorine at C2 and a nitro group at C5, enabling selective coupling reactions. The amine handle at C4 facilitates conjugation in synthetic pathways. This electron-deficient scaffold supports efficient derivatization under mild conditions, offering high stability and compatibility with diverse reaction environments.

Application

2-Chloro-5-nitropyrimidin-4-amine serves as a versatile building block in medicinal chemistry, enabling efficient construction of pyrimidine-based scaffolds. The chloro group facilitates nucleophilic substitution reactions, while the nitro and amine functionalities provide orthogonal handles for downstream functionalization. Its bench-stable nature and compatibility with standard coupling protocols make it well-suited for modular synthesis of heterocyclic compounds and API intermediates.
