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+
Inaccessible (Haz class 6.1 or 9), International	$108.00+
Accessible (Haz class 3, 4, 5 or 8), International	$238.00+

Description

Ethyl 3,5-dihydroxybenzoate features two hydroxyl groups at the meta positions relative to the ester, enabling enhanced solubility and reactivity in polar solvents. This configuration supports selective derivatization in synthetic routes requiring controlled polarity. The compound serves as a key intermediate for bioactive molecule scaffolds, particularly in polyphenolic and antioxidant analog development.

Application

Ethyl 3,5-dihydroxybenzoate serves as a versatile dihydroxy-substituted aromatic building block for medicinal chemistry and materials synthesis. Its two phenolic hydroxyl groups enable orthogonal functionalization, facilitating selective derivatization or protection strategies. The ester functionality supports downstream transformations such as hydrolysis or coupling reactions, while the compound exhibits good bench stability and ease of purification—ideal for use in multi-step syntheses of bioactive scaffolds and functional polymers.
