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

8-Bromochroman-4-one is a brominated chromanone derivative featuring a reactive ketone at the 4-position and a bromine substituent at the 8-position. This structural combination enables direct functionalization in cross-coupling reactions and facilitates downstream derivatization in medicinal chemistry. The molecule exhibits enhanced electrophilicity at the carbonyl carbon and improved solubility in polar organic solvents, streamlining its integration into synthetic workflows.

Application

8-Bromochroman-4-one serves as a versatile building block in medicinal chemistry, enabling late-stage functionalization and transition-metal-catalyzed cross-coupling reactions. Its bromine substituent at the C8 position provides high reactivity in Pd-mediated transformations, while the chroman-4-one core offers structural rigidity and compatibility with diverse synthetic manipulations. The compound exhibits excellent bench stability and facilitates efficient purification, making it well-suited for iterative synthesis workflows in API development.
