Pyridinium Dichromate (PDC), identified by CAS No. 20039-37-6, is a widely used chromium(VI) oxidizing reagent in organic synthesis. Known for its selectivity and efficiency, PDC is extensively utilized in pharmaceutical, fine chemical, and research applications. As demand for reliable oxidation reagents continues to grow, India has emerged as a key hub for the manufacture and supply of high-purity Pyridinium Dichromate to global markets.

Chemical Identity and Key Properties

Chemical Name: Pyridinium Dichromate

CAS Number: 20039-37-6

Molecular Formula: C₅H₆N·Cr₂O₇H

Appearance: Orange to reddish-orange crystalline solid

Grade: Research / Industrial / Export Quality

PDC is valued for its stability, ease of handling, and ability to perform selective oxidations under mild reaction conditions.

Role of Pyridinium Dichromate in Organic Chemistry

Pyridinium Dichromate is primarily used as a mild and selective oxidizing agent, especially for alcohol oxidation reactions.

Common Oxidation Applications

Primary alcohols → Aldehydes

Secondary alcohols → Ketones

Minimal over-oxidation to acids

Compatibility with sensitive functional groups

These characteristics make PDC a preferred alternative to harsher chromium oxidants in complex synthetic routes.

Applications Across Industries

1. Pharmaceutical Industry

PDC is widely used in the synthesis of active pharmaceutical ingredient (API) intermediates, where controlled oxidation is essential for maintaining compound purity and yield.

2. Fine Chemicals and Specialty Intermediates

Manufacturers rely on Pyridinium Dichromate for producing aldehydes, ketones, and heterocyclic intermediates used in agrochemicals, dyes, and specialty compounds.

3. Research & Development Laboratories

Due to its reproducibility and predictable reactivity, PDC is a standard reagent in academic institutions, CROs, and R&D labs.
