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

2-Hydroxy-5-(trifluoromethyl)benzaldehyde features a strategically positioned trifluoromethyl group that enhances electron-withdrawal and metabolic stability, while the adjacent phenolic hydroxyl enables hydrogen bonding and coordination in catalytic systems. This combination imparts unique reactivity in transition metal-catalyzed couplings and serves as a key building block in bioactive molecule synthesis.

Application

2-Hydroxy-5-(trifluoromethyl)benzaldehyde serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient access to substituted benzoxazole and benzothiazole scaffolds. Its ortho-hydroxyl and trifluoromethyl groups confer enhanced electronic modulation and metabolic stability, while the aldehyde functionality supports diverse transformations including reductive amination, nucleophilic addition, and condensation reactions. Bench-stable and readily purified by recrystallization, it functions reliably in standard synthetic workflows.
