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+

Description

This fluorenylmethoxycarbonyl-protected hexanoic acid derivative serves as a robust amino acid surrogate in peptide synthesis, featuring a stable C-terminal carboxylate and a photolabile fluorenylmethyl protecting group. The bulky fluorenyl moiety enhances solubility and minimizes racemization during coupling, while the aliphatic chain provides flexibility for backbone integration. Ideal for solid-phase and solution-phase protocols under standard conditions.

Application

2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)hexanoic acid serves as a robust N-terminal protecting group for amino acids in peptide synthesis, offering excellent stability under standard coupling conditions and facile removal via mild base treatment. Its fluorenylmethyl (Fmoc) moiety provides high functional group tolerance and enables efficient purification by standard chromatographic methods. The pendant hexanoic acid chain enhances solubility in organic solvents, facilitating use in both solution-phase and solid-phase synthesis workflows.
