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

(S)-3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-4-(4-chlorophenyl)butanoic acid features a chiral center at the 3-position, enabling stereoselective synthesis in peptide and pharmaceutical development. The fluorenylmethoxycarbonyl (Fmoc) group provides robust protection for amine functionalities, while the para-chlorophenyl moiety imparts enhanced lipophilicity and metabolic stability. This compound integrates seamlessly into solid-phase peptide synthesis workflows under standard conditions.

Application

(S)-3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-4-(4-chlorophenyl)butanoic acid serves as a well-established chiral building block for peptide synthesis and medicinal chemistry applications. The Fmoc-protected amine enables straightforward coupling reactions, while the para-chlorophenyl group provides structural rigidity and metabolic stability. Bench-stable and easily purified by chromatography, it functions reliably in standard solid-phase and solution-phase protocols.
