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

(E)-Methyl 4-methoxycinnamate features a conjugated trans-alkene system flanked by an electron-rich methoxy group and a polar ester moiety, enabling efficient incorporation into photoreactive frameworks. This bench-stable compound integrates readily into synthetic routes requiring extended π-conjugation or controlled reactivity under standard conditions.

Application

(E)-Methyl 4-methoxycinnamate serves as a versatile synthetic intermediate for the construction of styryl-containing architectures. Its conjugated enoate system enables reliable Michael additions, Diels–Alder cycloadditions, and palladium-catalyzed cross-coupling reactions. The methyl ester and para-methoxy substituent provide excellent stability, solubility in common organic solvents, and compatibility with diverse functional groups, facilitating straightforward purification and integration into multi-step syntheses.
