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+

Description

tert-Butyl 4-chloro-7,8-dihydropyrido[4,3-d]pyrimidine-6(5H)-carboxylate is a bench-stable heterocyclic building block featuring a chlorine-substituted pyridopyrimidine core. This electron-deficient scaffold integrates readily into medicinal chemistry campaigns, enabling direct access to bioactive scaffolds through late-stage functionalization. The tert-butyl ester group facilitates purification and stability during synthesis.

Application

tert-Butyl 4-chloro-7,8-dihydropyrido[4,3-d]pyrimidine-6(5H)-carboxylate serves as a versatile scaffold for constructing biologically relevant heterocycles, enabling efficient functionalization at the C4 position via palladium-catalyzed cross-coupling. The tert-butyl ester group provides excellent bench stability and facilitates straightforward deprotection under mild acidic conditions. Its compatibility with diverse nucleophiles and tolerance to common functional groups make it a practical building block in medicinal chemistry and process development workflows.
