    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

Boc-Ser(Tos)-OMe features a protected serine residue with a tosyl group at the hydroxyl and a methyl ester at the C-terminus, enabling stable incorporation into peptide sequences. This derivative facilitates efficient coupling under standard conditions while offering enhanced solubility and resistance to premature deprotection.

Application

Boc-Ser(Tos)-OMe serves as a robust, bench-stable amino acid building block for peptide synthesis, enabling efficient N-terminal protection and side-chain management. The tert-butyl carbamate (Boc) group provides orthogonal protection to the amine, while the tosyl (Tos) group offers reliable stabilization of the serine hydroxyl. This derivative facilitates smooth coupling reactions and simplifies purification due to enhanced solubility and stability under standard synthetic conditions.
