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
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

Ac-Glu(OtBu)-OH is a protected glutamic acid derivative featuring a tert-butyl ester on the side-chain carboxylate and acetyl group at the N-terminus. This configuration enables stable incorporation into peptide chains during solid-phase synthesis, offering enhanced solubility and resistance to racemization under standard coupling conditions.

Application

Ac-Glu(OtBu)-OH serves as a key building block in peptide synthesis, offering a protected glutamic acid residue with orthogonal functionality. The acetyl group at the N-terminus ensures stability and prevents undesired side reactions, while the tert-butyl ester selectively protects the side-chain carboxylate. This configuration facilitates efficient coupling in solid-phase and solution-phase peptide assembly, enabling reliable access to complex sequences and biologically relevant scaffolds.
