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.

Description

iST2-1 is a bench-stable, moisture-tolerant boronate ester featuring a sterically hindered aryl group that enables efficient cross-coupling under mild conditions. This reagent integrates seamlessly into Suzuki-Miyaura protocols, delivering high yields with minimal purification burden.

Application

iST2-1 serves as a robust building block for the synthesis of complex heterocyclic scaffolds, enabling efficient construction of pharmaceutically relevant core structures. Its well-defined reactivity profile supports reliable coupling and cyclization reactions under standard conditions, with demonstrated compatibility across diverse functional groups. Bench-stable and readily purified, it facilitates scalable synthesis workflows in medicinal chemistry and process development.
