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.

Type	HazMat Fee

Description

1-(tert-Butyl) 2-methyl 4-bromo-1H-pyrrole-1,2-dicarboxylate features a sterically shielded tert-butyl group and a brominated pyrrole core, enabling selective cross-coupling reactions. The electron-deficient pyrrole ring integrates readily into complex heterocyclic architectures under standard conditions. This bench-stable reagent streamlines access to functionalized pyrrole scaffolds in synthetic methodology.

Application

1-(tert-Butyl) 2-methyl 4-bromo-1H-pyrrole-1,2-dicarboxylate serves as a versatile pyrrolic building block for medicinal chemistry and heterocyclic synthesis. The bromo group enables palladium-catalyzed cross-coupling reactions, while the tert-butyl and methyl substituents provide steric and electronic tuning. Bench-stable and compatible with standard functional group manipulations, it facilitates efficient access to substituted pyrroles in multistep syntheses.
