    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

2,7-Di-tert-butyl-9H-fluoren-9-one features a sterically shielded fluorenone core with bulky tert-butyl groups at the 2 and 7 positions, enhancing stability and reducing reactivity at the carbonyl site. This configuration imparts exceptional bench stability and moisture tolerance, making it ideal for use in high-precision synthetic transformations where minimal side reactions are critical.

Application

2,7-Di-tert-butyl-9H-fluoren-9-one serves as a sterically hindered fluorenone scaffold with enhanced bench stability due to bulky tert-butyl groups at the 2 and 7 positions. It functions as a versatile building block in organic synthesis, enabling controlled functionalization at the C9 carbonyl site while maintaining resistance to decomposition. The protected fluorene core facilitates downstream transformations in catalytic systems and materials chemistry applications.
