For researchers involved in antioxidant studies, free radical scavenging assays, and biochemical investigations, sourcing reliable reagents is crucial. 2,2-Diphenyl-1-Picrylhydrazyl, commonly known as DPPH (CAS 1898-66-4), is a vital compound in this context. This article serves as a guide for researchers looking to buy DPPH, highlighting its applications and the critical factors in selecting a reputable supplier and manufacturer.

Understanding DPPH and Its Significance

DPPH is a stable free radical with a distinctive deep violet color in solution. Its unpaired electron makes it highly reactive towards compounds that can donate hydrogen atoms, such as antioxidants. The reaction leads to the formation of a colorless or pale yellow product, which can be quantified spectrophotometrically. This principle underpins its widespread use in various scientific applications:

  • Antioxidant Assays: DPPH is a primary reagent for evaluating the antioxidant activity of diverse compounds and extracts.
  • Biochemical Research: It is instrumental in studying reaction mechanisms involving free radicals.
  • EPR Standardization: DPPH serves as a standard for electron paramagnetic resonance (EPR) signal calibration.

Choosing the Right DPPH Supplier

When you need to purchase DPPH, quality and consistency are paramount. Look for suppliers who:

  • Offer High Purity: Ensure the DPPH meets the required assay standards (e.g., ≥95% or ≥96%).
  • Provide Certificates of Analysis (CoA): A CoA verifies the product's purity and specifications.
  • Have a Stable Supply Chain: Consistent availability is essential for ongoing research.
  • Offer Competitive Pricing: Compare quotes from different manufacturers and suppliers.
  • Provide Technical Support: Access to product information and handling advice is beneficial.
