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

Methyl 4-chloro-3-fluorobenzoate features a strategically positioned chloro and fluoro substituent on the aromatic ring, enabling precise electronic tuning for coupling reactions. This bench-stable ester integrates readily into synthetic sequences requiring orthogonal reactivity, delivering efficient access to functionalized aryl scaffolds under standard conditions.

Application

Methyl 4-chloro-3-fluorobenzoate serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient late-stage functionalization via palladium-catalyzed cross-coupling. Its ortho-halogenated aryl framework provides predictable reactivity for Suzuki, Stille, and Negishi couplings, while the ester group offers compatibility with standard deprotection and derivatization protocols. Bench-stable and readily purified by recrystallization or flash chromatography, it functions reliably in multi-step synthetic sequences requiring high functional group tolerance and predictable regiochemistry.
