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

(R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2,4-dimethylpentanoic acid serves as a chiral building block for peptide synthesis, featuring a sterically hindered side chain and a bench-stable fluorenylmethoxycarbonyl (Fmoc) protecting group. This configuration enables efficient incorporation into N-terminal protected amino acids with minimal racemization under standard coupling conditions.

Application

(R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2,4-dimethylpentanoic acid serves as a robust chiral building block for peptide synthesis, offering high stereoselectivity and bench stability. The Fmoc group enables efficient N-terminal protection with orthogonal deprotection under mild basic conditions. Its branched aliphatic side chain enhances solubility and reduces aggregation during solid-phase synthesis, facilitating purification and handling in iterative coupling workflows.
