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

Quinoxaline-5-carbaldehyde features a rigid heteroaromatic core with a strategically positioned aldehyde group, enabling direct integration into conjugated systems. This electron-deficient scaffold supports efficient coupling reactions and serves as a key building block in pharmaceutical intermediates and functional materials.

Application

Quinoxaline-5-carbaldehyde serves as a versatile building block in synthetic organic chemistry, enabling efficient construction of heterocyclic scaffolds through electrophilic and nucleophilic transformations. Its aldehyde functionality facilitates imine formation, reductive amination, and coupling reactions with amines or hydrazines, while the quinoxaline core provides structural rigidity and π-conjugation useful in medicinal chemistry and materials science. Bench-stable and readily purified by recrystallization, it functions reliably in multi-step syntheses requiring functional group compatibility and predictable reactivity.
