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

This fluorenylmethoxycarbonyl-protected diaminobenzoic acid derivative features two orthogonal functional handles for modular peptide synthesis. The fluoren-9-ylmethoxy carbonyl groups enable efficient N-terminal protection and removal under mild basic conditions, while the carboxylic acid moiety facilitates coupling reactions. Designed for precision in solid-phase and solution-phase peptide assembly workflows.

Application

3,4-Bis((((9H-fluoren-9-yl)methoxy)carbonyl)amino)benzoic acid serves as a versatile dipeptide-building block for solid-phase peptide synthesis, enabling efficient Nα-protected amino acid coupling. The fluorenylmethoxycarbonyl (Fmoc) groups provide excellent stability under basic conditions and facilitate clean deprotection with piperidine. Its ortho-diamino-benzoic acid core offers a rigid scaffold suitable for constructing bioactive peptide sequences and heterocyclic systems, with high functional group tolerance and ease of purification via standard chromatographic methods.
