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+

Description

Camphorsulfonic acid is a organosulphur compound.Camphor-10-sulfonic acid () (CSA) is extensively used as an acid catalyst.It can be used in a catalytic amount to protect hydroxyl groups as tetrahydropyranyl (THP) ethers using dihydropyran.It also catalyzes the protection of ketones as ketals.It is a useful catalyst for the intramolecular ring opening of epoxides.CSA can also be used to catalyze nucleophile-promoted alkyne-iminium cyclization in the total synthesis of pumiliotoxin A.

Application

(±)-Camphor-10-sulfonic acid serves as a chiral, bench-stable sulfonic acid reagent widely used in asymmetric synthesis and catalysis. Its rigid terpene backbone provides excellent stereochemical control in enantioselective transformations, while the sulfonic acid group enables efficient protonation, activation, and phase-transfer applications. Functions effectively in esterifications, sulfonations, and as a catalyst or resolving agent in industrial-scale processes requiring high reproducibility and functional group tolerance.
