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

2,6-Dichloropyrimidine-4,5-diamine features two chlorine substituents at the 2 and 6 positions flanking a diamino-functionalized pyrimidine core. This electron-deficient heterocycle serves as a key building block in medicinal chemistry, enabling direct incorporation into kinase inhibitors and antiviral agents through facile nucleophilic substitution. The diamine moiety provides versatile conjugation handles for further derivatization under standard conditions.

Application

2,6-Dichloropyrimidine-4,5-diamine serves as a versatile building block in medicinal chemistry, enabling efficient construction of pyrimidine-based scaffolds. Its two chloro groups facilitate nucleophilic substitution reactions, while the diamine functionality offers orthogonal reactivity for coupling and derivatization. The compound demonstrates bench stability and compatibility with standard purification methods, making it well-suited for iterative synthesis workflows in API development and heterocyclic library generation.
