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

Description

(R)-tert-Butyl 1,4-oxazepan-6-ylcarbamate is a chiral oxazepane scaffold featuring a bench-stable carbamate protecting group. This configuration enables direct incorporation into complex heterocyclic architectures, particularly in the synthesis of bioactive small molecules. The tertiary butyl moiety enhances solubility and stability during multi-step transformations, while the oxazepane ring provides conformational rigidity for targeted ligand design.

Application

(R)-tert-Butyl 1,4-oxazepan-6-ylcarbamate serves as a valuable chiral building block for the synthesis of bioactive heterocycles, particularly in medicinal chemistry and API development. Its oxazepane core provides a rigid, conformationally constrained scaffold with favorable solubility and metabolic stability. The carbamate group enables selective deprotection under mild acidic conditions, facilitating downstream functionalization. The (R)-configuration ensures stereochemical fidelity in complex molecule assembly, making it a reliable intermediate in asymmetric synthesis workflows.
