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.

Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

3,4-Dichloro-1H-pyrrole-2,5-dione features a highly electron-deficient pyrrolinedione core with chlorine substituents at the 3- and 4-positions, enhancing its reactivity in cycloaddition and electrophilic substitution processes. This bench-stable compound serves as a key building block in heterocyclic synthesis, particularly for constructing complex nitrogen-containing frameworks under mild conditions.

Application

3,4-Dichloro-1H-pyrrole-2,5-dione serves as a versatile dienophile in Diels-Alder reactions and functions as a key building block for heterocyclic scaffolds. Its electron-deficient pyrrolinedione core enables efficient cycloadditions with dienes, offering high regioselectivity and stability under standard reaction conditions. The dichloro substitution enhances reactivity while maintaining bench stability, facilitating straightforward purification and integration into synthetic sequences targeting complex molecular architectures.
