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
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+
Inaccessible (Haz class 6.1 or 9), International	$108.00+

Description

4-Methyl-3,4-dihydronaphthalen-1(2H)-one is a bench-stable, electron-rich heterocyclic ketone featuring a fused bicyclic scaffold with a methyl substituent at the 4-position. This structure integrates a partially saturated naphthalene core with a carbonyl group, enabling direct incorporation into synthetic sequences for natural product analogs and functional materials.

Application

4-Methyl-3,4-dihydronaphthalen-1(2H)-one serves as a versatile scaffold in medicinal chemistry, enabling the synthesis of bioactive compounds through established functionalization at the dihydroaromatic ring. Its stability under standard reaction conditions and compatibility with common transformations—such as oxidation, electrophilic substitution, and palladium-catalyzed coupling—facilitate efficient access to complex heterocyclic systems and API intermediates.
