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

5-Bromo-4-chloro-1H-indole is a halogenated indole scaffold featuring bromine at the 5-position and chlorine at the 4-position, offering enhanced electronic modulation and steric profile. This electron-deficient heterocycle integrates readily into pharmaceutical intermediates and bioactive molecule synthesis, providing high functional group tolerance under standard coupling conditions.

Application

5-Bromo-4-chloro-1H-indole serves as a versatile building block for the synthesis of biologically active heterocycles and pharmaceutical intermediates. Its well-defined substitution pattern enables selective functionalization at the indole core, facilitating cross-coupling reactions and C–H activation processes. The molecule exhibits good bench stability and compatibility with standard purification methods, making it suitable for iterative synthetic sequences in medicinal chemistry and process development workflows.
