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

2,4,6-Trichloropyrimidin-5-amine features three chlorine substituents at key positions on the pyrimidine ring, enabling robust coupling reactions in synthetic chemistry. This electron-deficient heterocycle serves as a pivotal scaffold for constructing pharmaceutical intermediates and functional materials. The amine group facilitates nucleophilic substitution, while the trichloro pattern enhances reactivity under mild conditions. Bench-stable and moisture-tolerant, it streamlines access to complex architectures in medicinal chemistry and agrochemical development.

Application

2,4,6-Trichloropyrimidin-5-amine serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient construction of heterocyclic scaffolds. Its three chlorine substituents provide orthogonal reactivity for nucleophilic substitution, facilitating the introduction of diverse amine, thiol, or ether functionalities. The compound exhibits excellent bench stability and is compatible with standard reaction conditions, making it a practical choice for modular synthesis workflows.
