The PDC (Pyridinium Dichromate) is a common oxidising agent in organic chemistry and is classified as an oxidizing agent by CAS 20039-37-6. In addition, pyridinium dichromate has the advantage of being able to regiospecifically oxidise either primary or secondary alcohols to give either an aldehyde or ketone respectively under mild reaction conditions. High purity pyridinium dichromate is manufactured in strict accordance with the requirements of the pharmaceutical, chemical and research industries at NSR Laboratories.

Key Properties
PDC offers several important properties that contribute to its effectiveness:
Molecular Formula: C₁₀H₁₀Cr₂N₂O₇
Appearance: Orange crystalline powder
Solubility: Soluble in polar organic solvents such as DMF
Reactivity: Mild and selective oxidizing agent
Stability: Stable under proper storage conditions
At NSR Laboratories, strict quality control ensures that CAS 20039-37-6 is delivered with high purity and consistency for industrial use.
Synthesis of Pyridinium Dichromate
PDC is typically synthesized by reacting chromium trioxide with pyridine in the presence of an acid, usually hydrochloric acid.
General synthesis process:
- Chromium trioxide is dissolved in water.
- Pyridine is added gradually under controlled temperature.
- Acid is introduced to facilitate the formation of the pyridinium salt.
- The product precipitates as orange crystals, which are filtered and dried.
The manufacturing process at NSR Laboratories ensures safe handling, controlled reactions, and consistent production quality of CAS 20039-37-6.
