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
Excepted Quantity	$0.00

Description

3-Bromo-5-methoxyphenol features a bromine substituent at the meta position relative to a hydroxyl group, combined with a methoxy group at the para position, creating a uniquely activated aromatic scaffold. This electronic configuration enables selective coupling reactions in cross-coupling and functionalization workflows. The compound exhibits enhanced solubility in organic solvents and stability under standard bench conditions, facilitating its use in synthetic pathways requiring precise regiocontrol.

Application

3-Bromo-5-methoxyphenol serves as a versatile building block in medicinal chemistry and materials science, enabling direct functionalization via palladium-catalyzed cross-coupling reactions. Its bromine and phenolic hydroxyl groups offer orthogonal reactivity for sequential modifications, while the methoxy group enhances solubility and modulates electronic properties. Bench-stable and readily purified by recrystallization, it functions efficiently in Suzuki, Stille, and Negishi couplings, facilitating rapid access to substituted aromatic scaffolds relevant to pharmaceutical and agrochemical development.
