Packaging and Transportation Precautions for TEMPO (2,2,6,6-Tetramethylpiperidine-1-oxyl)

  2,2,6,6-Tetramethylpiperidine-1-oxyl (TEMPO, CAS: 2564-83-2) is a stable free radical compound commonly used as an oxidant and catalyst, widely applied in pharmaceuticals, materials science, and agrochemical fields.

 With a melting point of 36–38°C, this property brings about certain unavoidable challenges in the packaging and transportation of the product. As a manufacturer of TEMPO with years of experience in its production and sales, we have summarized the following key precautions for its packaging and transportation for our customers’ reference. For more detailed technical data, please contact our sales team.

1. Packaging formats based on quantity:

Our standard packaging is 25 kg per plastic drum, lined with a PP plastic bag. We also offer customized packaging services for any quantity. No matter how much you purchase, we ensure stable and secure packaging. Due to the relatively low melting point of the product—especially in summer when the temperature during transit may exceed the melting point—partial melting may occur. To address this, our gram- and kilogram-level packaging includes tight sealing measures. For example, fluorinated bottles are sealed with aluminum foil, followed by waterproof tape for enhanced security, ensuring no leakage occurs during transportation.

2. Product stability of TEMPO:

Considering that partial melting may occur during routine transportation, we have conducted comprehensive stability testing on TEMPO to ensure quality is not compromised. Samples of TEMPO are sealed and placed in a constant-temperature oven at 40°C. Every two days, we test parameters such as chromatographic purity, moisture content, and ash content, maintaining detailed records and compiling a comprehensive stability report. The tests show that partial melting does not affect the quality of TEMPO. Customers can rest assured. However, if you wish to completely avoid melting, please contact us for specialized cold-chain transportation arrangements.
