    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

trans-Urocanic acid features a stable, planar trans-configuration at the C2–C3 double bond, enhancing its resistance to isomerization under ambient conditions. This structural rigidity supports consistent performance in photochemical studies and biological assays where stereochemical integrity is critical.

Application

trans-Urocanic acid serves as a stable, bench-ready building block for the synthesis of pyrrolidine-based heterocycles and bioactive molecules. Its defined stereochemistry and carboxylic acid functionality enable reliable coupling reactions and derivatization under standard conditions. The molecule functions effectively in peptide-like conjugations and offers predictable reactivity in nucleophilic substitution and cyclization protocols.
