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

Z-Tyr(tBu)-OH is a protected tyrosine derivative featuring a benzyloxycarbonyl (Z) group at the N-terminus and a tert-butyl ester at the phenolic oxygen. This configuration enables selective incorporation into peptide chains during solid-phase synthesis, offering enhanced stability and reduced side reactions under standard coupling conditions.

Application

Z-Tyr(tBu)-OH serves as a protected tyrosine building block for peptide synthesis, offering stable handling and orthogonal protection. The benzyloxycarbonyl (Z) group enables selective deprotection under mild hydrogenolysis, while the tert-butyl ester facilitates efficient coupling and subsequent cleavage. This dual protection scheme supports high-yielding amide bond formation in standard solid-phase and solution-phase workflows, making Z-Tyr(tBu)-OH a reliable scaffold for synthesizing bioactive peptides and peptidomimetics.
