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+

Description

This fluorenylmethoxycarbonyl-protected lysine derivative enables efficient solid-phase peptide synthesis, featuring a tert-butyl ester that facilitates selective deprotection under mild acidic conditions. The fluoren-9-ylmethoxycarbonyl (Fmoc) group ensures high coupling efficiency and stability during chain elongation, while the hydrochloride salt enhances solubility in common organic solvents.

Application

tert-Butyl (((9H-fluoren-9-yl)methoxy)carbonyl)-L-lysinate hydrochloride serves as a robust, bench-stable amino acid derivative enabling efficient N-terminal protection in peptide synthesis. The Fmoc group facilitates orthogonal deprotection under mild basic conditions, while the tert-butyl ester permits selective side-chain modulation. This reagent exhibits excellent solubility and functional group tolerance, streamlining sequence assembly in solid-phase and solution-phase workflows.
