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-Dichloropyrido[3,2-d]pyrimidine serves as a critical heterocyclic scaffold in medicinal chemistry, featuring two chlorine substituents that enable selective electrophilic substitution and enhance metabolic stability. This electron-deficient core integrates readily into kinase inhibitors and antiviral agents, offering high reactivity under standard coupling conditions.

Application

2,4-Dichloropyrido[3,2-d]pyrimidine serves as a versatile building block in medicinal chemistry, enabling efficient construction of purine-like scaffolds through nucleophilic substitution. Its dichloro substitution pattern facilitates sequential functionalization at C2 and C4 positions, offering high regioselectivity in cross-coupling and heterocycle formation. The compound exhibits excellent bench stability and compatibility with standard synthetic protocols, making it a reliable reagent for the development of kinase inhibitors and other bioactive heterocycles.
