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-(o-tolyl)butanoic acid is a chiral, bench-stable amino acid derivative featuring a fluorenylmethoxycarbonyl (Fmoc) protecting group and an ortho-tolyl substituent. This configuration enables efficient incorporation into peptide synthesis workflows, where the Fmoc group facilitates orthogonal deprotection and the sterically hindered side chain enhances sequence fidelity during coupling steps.

Application

(S)-3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-4-(o-tolyl)butanoic acid serves as a valuable chiral building block for the synthesis of bioactive peptides and pharmaceutical intermediates. The Fmoc group enables efficient solid-phase peptide synthesis, while the (S)-configured α-amino acid side chain provides stereochemical control. Its bench-stable nature and compatibility with standard coupling conditions facilitate reliable purification and integration into complex molecular architectures.
