    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

3-(2-Bromoethyl)-3-methyl-3H-diazirine is a photoactivatable crosslinker featuring a reactive diazirine ring and a bromoethyl tether. This combination enables site-specific, UV-induced covalent labeling of proximal biomolecules. The molecule demonstrates robust stability under ambient conditions and facilitates efficient conjugation in biological systems.

Application

3-(2-Bromoethyl)-3-methyl-3H-diazirine serves as a versatile photoaffinity labeling reagent, enabling site-specific protein crosslinking upon UV irradiation. The bromoethyl side chain facilitates conjugation via nucleophilic substitution, while the diazirine ring provides high photoreactivity and stability under ambient conditions. This compound functions effectively in biological target identification workflows, offering reliable attachment to amino acid residues with minimal background reactivity.
