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

(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)(methyl)amino)-3-(4-methoxyphenyl)propanoic acid is a chiral building block featuring a fluorenylmethoxycarbonyl (Fmoc) protected amine and a para-methoxyphenyl side chain. This configuration enables direct incorporation into peptide synthesis workflows, where the Fmoc group facilitates efficient, orthogonal deprotection under mild basic conditions. The molecule combines steric control from the chiral center with enhanced solubility and stability during solid-phase assembly.

Application

(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)(methyl)amino)-3-(4-methoxyphenyl)propanoic acid serves as a versatile chiral building block for peptide synthesis and medicinal chemistry campaigns. The Fmoc-protected α-amino acid exhibits excellent bench stability, facilitates efficient coupling reactions, and enables straightforward purification via standard chromatographic methods. Its methylated amine side chain enhances solubility and reduces racemization during activation, making it well-suited for iterative solid-phase and solution-phase syntheses of complex peptidomimetics and bioactive scaffolds.
