    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

Intercalating into DNA duplexes, Methyl Blue (CAS 28983-56-4) enables consistent polychrome histological staining of human tissue sections through stable chromogenic binding and controlled dye concentration.

Application

Methyl Blue (CAS 28983-56-4) serves as a vital biological stain in microbiology and histology, enabling clear visualization of cellular structures under microscopy for diagnostic and research purposes. It reveals hidden details with precision. This dye also functions as a reliable pH indicator, shifting color across acidic and basic ranges—ideal for lab experiments and student training. Its redox activity makes it indispensable in titrations, where oxidation state changes track reaction progress. Industrial dyers favor it for vibrant, stable fabric coloring. Environmental analysts deploy it to detect pollutants in water systems.
