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

5-Bromo-4-chloro-7H-pyrrolo[2,3-d]pyrimidine delivers a highly reactive heterocyclic scaffold for medicinal chemistry applications. This electron-deficient purine analog integrates readily into kinase inhibitors and nucleoside analogs, offering enhanced metabolic stability. The bromo and chloro substituents enable efficient cross-coupling transformations under mild conditions, facilitating rapid diversification of core structures.

Application

5-Bromo-4-chloro-7H-pyrrolo[2,3-d]pyrimidine serves as a versatile building block in the synthesis of purine-based scaffolds. Its orthogonal halogenation pattern enables sequential cross-coupling reactions with high regiocontrol, facilitating the construction of biologically relevant heterocycles. The compound exhibits excellent bench stability and is compatible with standard Pd-catalyzed transformations, simplifying purification and scale-up in medicinal chemistry campaigns.
