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

Description

1-(4-Fluorophenyl)-1H-pyrazole-4-carbaldehyde features a fluorinated phenyl ring linked to a pyrazole core bearing an aldehyde functional group. This electron-deficient scaffold enables direct coupling in transition-metal-catalyzed reactions and serves as a key building block for bioactive heterocycles. The compound exhibits enhanced metabolic stability and solubility under standard bench conditions, facilitating integration into medicinal chemistry campaigns.

Application

1-(4-Fluorophenyl)-1H-pyrazole-4-carbaldehyde serves as a versatile building block in medicinal chemistry, enabling the synthesis of heterocyclic scaffolds through standard condensation and coupling reactions. The aldehyde functionality facilitates efficient derivatization via reductive amination, Grignard additions, or Wittig transformations, while the fluorinated aryl group enhances metabolic stability and modulates electronic properties. Bench-stable and readily purified by recrystallization, it functions reliably in multi-step syntheses targeting bioactive molecules.
