Royalchem supplies premium Phosphotungstic Acid (PTA). It is widely recognized as a robust acid catalyst in organic synthesis and a critical reagent in biological staining (Masson's Trichrome). We ensure strict moisture control packaging to prevent deliquescence during transit.
Molecular Formula:
H₃PW₁₂O₄₀ · xH₂O
(Keggin Structure)
Molecular Weight:
2880.05 (Anhydrous basis)
Used as a strong, eco-friendly acid catalyst for hydration of alkenes, polymerization, and alkylation reactions. It offers high catalytic activity and stability.
Essential component in Masson's Trichrome Stain and phosphotungstic acid-hematoxylin (PTAH) stains. Used to visualize collagen, muscle fibers, and fibrin.
Precipitating agent for proteins, alkaloids, and amino acids. Used in the manufacturing of pigment lakes (precipitating basic dyes) to improve lightfastness.
Standard Packaging:
• 25kg Drums (Fiber or Plastic)
• Tightly sealed to prevent moisture absorption.
Storage Conditions:
Store at room temperature (15°C to 25°C). Keep in a dry, well-ventilated place. Corrosive substance – handle with appropriate PPE.
