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
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+

Description

Ethyl 3-bromo-2-methylbenzoate features a brominated aromatic ring with ortho-methyl and ester substituents, enabling direct functionalization in cross-coupling reactions. The electron-deficient bromine facilitates palladium-catalyzed transformations, while the ethyl ester group offers synthetic handle for further derivatization. This bench-stable reagent integrates efficiently into complex molecule assembly.

Application

Ethyl 3-bromo-2-methylbenzoate serves as a versatile building block in synthetic organic chemistry, enabling palladium-catalyzed cross-coupling reactions due to its well-defined bromine electrophilicity. The ester and methyl groups offer orthogonal functional handles for further derivatization, while the benzoate core provides structural rigidity and compatibility with standard purification techniques. Its bench-stable nature facilitates reliable use in multi-step synthesis of complex scaffolds.
