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

Tween-20 is a polysorbate-based non-ionic surfactant. It is made up of three chemical units: aliphatic ester chains that hinder biomolecules from nonspecific interactions aliphatic chain that can be non-covalently adsorbed on a hydrophobic surfacehydrophilic terminal hydroxyl groups, which can be chemically modified for potential applications.Tween-20 can be used as a structure-directing agent in the preparation of mesoporous oxide films because of its ability to promote textural properties of the films such as controllable crystallinity, film morphology, tailor-designed pore structure, high BET surface area, and controlled film thickness. It is also used in the synthesis of AuNPs/TWEEN/GO composites, where Tween-20 acts as a reducing and immobilizing agent for AuNPs (Au nanoparticles) as well as a stabilizing agent for GO (graphene oxide).Tween-20 can also be used as an emulsifying, solubilizing, and wetting agent in a variety of liquid formulations.

Application

Captopril EP Impurity D serves as a well-characterized reference standard for the detection and quantification of a key impurity in captopril synthesis. It functions as a critical control in quality assurance workflows, enabling accurate assessment of batch consistency and degradation pathways. Its defined structure facilitates reliable HPLC method development and compliance with pharmacopeial specifications.
