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+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+
Inaccessible (Haz class 6.1 or 9), International	$108.00+
Accessible (Haz class 3, 4, 5 or 8), International	$238.00+

Description

Ac-Met-OMe is a bench-stable, moisture-tolerant acetylated methionine methyl ester featuring a protected thioether side chain. This derivative enables direct incorporation into peptide sequences without requiring additional protection strategies, streamlining synthesis workflows in peptide-based drug discovery and chemical biology applications.

Application

Ac-Met-OMe serves as a versatile building block for peptide synthesis, enabling the incorporation of methionine derivatives with a protected N-terminus and esterified C-terminus. Its acetyl group enhances stability and solubility, while the thioether side chain offers reliable reactivity in standard coupling protocols. The compound facilitates efficient access to bioactive peptides and is well-suited for bench-scale applications requiring orthogonal protection and minimal handling complexity.
