Orthotolidine | Restricted/Hazardous Shipment, 1 Pint (473 mL)
Description
Orthotolidine [PN: T-10-123], also known as o-tolidine, is an organic compound that is typically colorless. Used in pool water kits for chlorine detection, it is a colorimetric indicator to determine whether there was chlorine in residual water. Upon detecting chlorine, a yellow-colored compound would be produced. This compound is also used in various applications, such as dye production; analytical, clinical, and forensic chemistry; and swimming pool water.
The reagent is sold in 1 pint (16 oz/473 mL) bottles made of plastic.
Please note, this is considered HAZMAT FOR AIR SHIPMENTS.

Storage Instructions
All reagents have a shelf life, whether they are liquids, powders, crystals, tablets, or test-strip pads. If kept dry, powders and crystals are very stable; acids are also long lived. Date of manufacture is not the controlling factor when it comes to shelf life storage conditions are more important.
To this end, we recommend:
- Storing reagents at a consistent temperature in the range if 3685F (229C); extreme temperature fluctuation, say from a refrigerator to a hot car trunk, causes reagents to deteriorate.
- Keeping them out of prolonged direct sunlight. (Note: their brown plastic bottles help protect very light-sensitive reagents.)
- Segregating reagents from containers of treatment chemicals.
- Replacing caps immediately and tightening them carefully so that exposure to air and humidity is limited.
- Avoiding switching bottle caps, placing bottle caps on soiled surfaces, repouring reagents into contaminated containers, or touching test strips
