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

5-aminofluorescein is also used to prepare FITC Isomer I (CDX-F0011, CDX-F0020). It is a chemical used as molecular probe and important as fluorescent dye and for derivatives. Fluorescent labeling reagent for proteins. Used in the fluorescent antibody technique for rapid identification of pathogens.

Application

1(2H)-Isoquinolinone serves as a versatile heterocyclic building block in medicinal chemistry, enabling efficient access to isoquinoline-based scaffolds. Its stable, planar structure facilitates electrophilic substitution and transition-metal-catalyzed coupling reactions. The carbonyl group at the C1 position offers site-specific functionalization potential, while the core exhibits favorable solubility and bench stability for routine synthetic workflows.
