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+

Description

Methyl 3,4-dihydroxybenzoate features two adjacent hydroxyl groups on the aromatic ring, enhancing solubility and reactivity in synthetic transformations. This ortho-dihydroxy motif enables efficient metal chelation and serves as a key scaffold in bioactive molecule design. The methyl ester group offers stability under standard conditions while permitting selective hydrolysis for downstream derivatization.

Application

Methyl 3,4-dihydroxybenzoate serves as a versatile building block in synthetic organic chemistry, enabling access to bioactive phenolic scaffolds and natural product analogs. Its ortho-dihydroxy functionality facilitates oxidation to quinones, complexation with metals, and derivatization under standard conditions. The methyl ester group provides stability and compatibility with diverse transformations, including hydrogenation, nucleophilic substitution, and coupling reactions. This compound exhibits excellent bench stability and ease of purification, making it well-suited for medicinal chemistry campaigns and process development workflows.
