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

Description

This pyrano[3,2-d]pyrimidine scaffold integrates electron-deficient halogen substituents at the 2,4-positions, enhancing its reactivity in cross-coupling transformations. The fused dihydro-pyran ring imparts conformational rigidity and improved solubility in polar aprotic solvents, enabling efficient incorporation into complex heterocyclic architectures under standard conditions.

Application

2,4-Dichloro-7,8-dihydro-6H-pyrano[3,2-d]pyrimidine serves as a versatile building block in heterocyclic synthesis, enabling efficient access to pyrano[3,2-d]pyrimidine scaffolds prevalent in medicinal chemistry. Its dichloro substitution pattern facilitates downstream functionalization via nucleophilic displacement, while the dihydro-pyrano core exhibits bench stability and compatibility with standard reaction conditions. The compound functions effectively in Pd-catalyzed cross-coupling and cycloaddition protocols, supporting scalable route development for advanced intermediates.
