Description

CAS 643-79-8 O-Phthalaldehyde OPA HPLC Grade Derivatization Reagent

Our O-Phthalaldehyde (OPA) CAS 643-79-8 is a premium HPLC-grade derivatization reagent with ≥99% purity, specifically optimized for amino acid analysis. Widely used in pre-column and post-column derivatization protocols, this ortho-phthaldialdehyde reagent reacts rapidly with primary amines in the presence of thiol compounds to form highly fluorescent isoindole derivatives.

Key Features

  • Purity ≥99% — minimal background interference for sensitive HPLC detection
  • CAS 643-79-8 molecular identity guaranteed by COA
  • Yellow crystalline powder, readily soluble in methanol or ethanol
  • Excellent batch-to-batch consistency for reproducible results

Applications

Ideal for amino acid quantification in protein hydrolysates, physiological fluids, and food samples. Compatible with C18 reverse-phase columns and fluorescence detection (ex 340 nm / em 455 nm).

Packaging

Available in 1g, 5g, 10g, 25g, and bulk quantities. Sealed under nitrogen in amber glass vials for long-term stability.
