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+

Description

Oxazolo[4,5-b]pyridine delivers a rigid, electron-deficient heterocyclic scaffold ideal for constructing bioactive molecules. This fused system combines nitrogen-rich functionality with planar geometry, enabling strong π-stacking interactions and enhanced metabolic stability in pharmaceutical applications.

Application

Oxazolo[4,5-b]pyridine serves as a privileged heterocyclic scaffold in medicinal chemistry, offering enhanced metabolic stability and favorable pharmacokinetic properties. Its fused tricyclic structure enables robust functionalization at multiple positions, facilitating diverse downstream modifications. The core exhibits excellent bench stability, tolerates common reaction conditions, and functions effectively in cross-coupling and nucleophilic substitution processes, making it a valuable building block for the synthesis of targeted small-molecule libraries and advanced API intermediates.
