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.

Description

This protected amino acid derivative features a tert-butoxycarbonyl group that stabilizes the amine functionality, enabling reliable incorporation into peptide synthesis workflows. The para-chloro substituent enhances electrophilic reactivity and provides a handle for downstream functionalization. Designed for robust handling under standard bench conditions, this compound integrates seamlessly into multi-step organic transformations requiring controlled nitrogen protection and strategic halogen placement.

Application

4-((tert-Butoxycarbonyl)amino)-2-chlorobenzoic acid serves as a versatile building block in medicinal chemistry, enabling the synthesis of substituted benzimidazoles and other heterocyclic scaffolds. The protected amine and carboxylic acid functionalities offer orthogonal reactivity, facilitating sequential transformations in multi-step syntheses. Its bench-stable nature and compatibility with standard coupling protocols make it ideal for peptide-like and small-molecule library development.
