    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

Orange G (C.l. 16230) is the disodium salt of benzeneazo-2-naphthol-6,8-disulfonic acid, C16H10N2O7S2Na2. Orange G, also known as wool orange 2G, is a component in several industry applications including cytology, histology, biology, and industrial staining. It is a component of Mallorys connective tissue stain.Orange G is typically used as a background or cytoplasmic stain for various biological samples including a common application within clincial cytology within Papanicolaou varients.

Application

Propargyl-PEG4-acid serves as a versatile, bench-stable linker for bioconjugation and modular synthesis. Its terminal alkyne enables efficient copper-catalyzed azide-alkyne cycloaddition (CuAAC), while the carboxylic acid facilitates amide coupling or activation under standard conditions. The PEG4 spacer provides solubility and reduces non-specific binding, making it ideal for constructing functionalized probes, polymer architectures, and drug delivery systems with predictable reactivity and ease of purification.
