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-formyl-2-methylbenzoate features a formyl group at the para position relative to the ester, creating a highly reactive electrophilic site ideal for nucleophilic additions. The adjacent methyl substituent provides steric and electronic modulation, enhancing stability while preserving reactivity in coupling processes. This aromatic aldehyde ester integrates readily into complex molecule synthesis under mild conditions.

Application

Methyl 4-formyl-2-methylbenzoate serves as a versatile building block in synthetic organic chemistry, enabling efficient access to substituted benzaldehyde derivatives and heterocyclic scaffolds. Its formyl group facilitates nucleophilic additions, condensations, and cyclizations, while the methyl ester supports selective transformations. The molecule exhibits good bench stability and is readily purified by standard chromatographic methods, making it well-suited for iterative synthesis workflows in medicinal chemistry and process development.
