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-1-methyl-2-oxoindoline is a bench-stable, electron-deficient indoline derivative featuring a bromine substituent at the 5-position and a methyl group at nitrogen. This scaffold integrates readily into heterocyclic synthesis, serving as a key intermediate for medicinal chemistry applications. The para-brominated framework enables direct functionalization via palladium-catalyzed cross-coupling reactions.

Application

5-Bromo-1-methyl-2-oxoindoline serves as a versatile building block for the synthesis of substituted indoline scaffolds prevalent in medicinal chemistry. Its bromine substituent enables palladium-catalyzed cross-coupling reactions, while the 2-oxo group provides a handle for further functionalization. The compound exhibits good bench stability and is readily purified by standard chromatographic methods, facilitating integration into multi-step synthetic sequences for API development.
