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

Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

Tert-butyl L-alaninate is a bench-stable, moisture-tolerant amino acid derivative featuring a protected L-alanine side chain. This sterically hindered ester integrates seamlessly into peptide synthesis workflows, offering improved solubility and handling over traditional alanine precursors.

Application

Tert-butyl L-alaninate serves as a stable, bench-ready amino acid derivative enabling efficient amide bond formation and peptide coupling workflows. Its tert-butyl ester functionality provides excellent stability under basic conditions while allowing straightforward deprotection with mild acids. The L-alanine backbone offers predictable stereochemical control in asymmetric synthesis, making it a reliable building block for peptidomimetics and heterocyclic scaffolds.
