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

2-Oxoindoline-6-carboxylic acid features a fused indoline core with a ketone at the 2-position and a carboxylic acid at the 6-position, providing a rigid, electron-deficient scaffold. This structural motif enables direct incorporation into bioactive molecules, particularly in kinase inhibitor design and medicinal chemistry campaigns requiring polar, planar heterocyclic units. The molecule exhibits bench-stable handling characteristics and compatibility with standard peptide coupling protocols.

Application

2-Oxoindoline-6-carboxylic acid serves as a versatile building block in medicinal chemistry, enabling the construction of indoline-based heterocycles prevalent in kinase inhibitors and CNS-targeted therapeutics. Its orthogonally protected amine and carboxylic acid functionalities facilitate efficient peptide coupling, cyclization, and derivatization under standard synthetic conditions. Bench-stable and amenable to purification via recrystallization or chromatography, it functions reliably in multi-step syntheses requiring functional group tolerance and predictable reactivity.
