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

tert-Butyl (S)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-aminopropanoate hydrochloride serves as a protected chiral amino acid building block featuring a fluorenylmethoxycarbonyl (Fmoc) group and a tert-butyl ester. This derivative enables efficient solid-phase peptide synthesis with orthogonal protection, offering excellent stability under standard conditions and clean deprotection during chain elongation.

Application

tert-Butyl (S)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-aminopropanoate hydrochloride serves as a protected chiral amino acid building block for peptide synthesis, enabling efficient incorporation of (S)-β-alanine derivatives. The Fmoc group provides orthogonal protection for the amine, while the tert-butyl ester allows selective deprotection under mild acidic conditions. Its stability under standard synthetic handling and compatibility with common coupling reagents facilitate reliable use in solid-phase and solution-phase workflows.
