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-Bromo-5-pyrimidinamine features a bromine atom at the 2-position and an amino group at the 5-position of the pyrimidine ring, creating a versatile scaffold for nucleophilic substitution and cross-coupling reactions. This electron-deficient heterocycle enables efficient derivatization in medicinal chemistry and materials science applications.

Application

2-Bromo-5-pyrimidinamine serves as a versatile building block in medicinal chemistry, enabling efficient access to pyrimidine-based scaffolds through palladium-catalyzed cross-coupling reactions. Its bromine atom facilitates reliable C–X bond formation with aryl, heteroaryl, and alkyl boron reagents under standard Suzuki conditions. The amine group provides orthogonal reactivity for derivatization, while the compound exhibits excellent bench stability and ease of purification, making it well-suited for high-throughput synthesis and API intermediate development.
