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

An excellent derivative for the introduction of Arg in Fmoc SPPS. The Pmc group is removed by TFA in 1-3 hours [1,2,3]. For discussions on the side-reactions associated with the use of sulfonyl-based arginine protection, see [4,5,6,7,8,9,10,11]. In the synthesis of peptides containing both Arg and Trp, it is recommended that this derivative is used in conjunction with Fmoc-Trp(Boc)-OH (852050) [5,6,11].

Application

1-(Pyridin-3-yl)ethanone serves as a versatile building block in medicinal chemistry, enabling direct functionalization at the pyridine ring and facilitating C–C bond formation via enolate chemistry. Its stability under standard reaction conditions and compatibility with common protecting groups make it suitable for multi-step synthesis of heterocyclic scaffolds and API intermediates.
