HL-Synthetic Capsaicin (Nonivamide, PAVA) > 98% Purity

HL-Synthetic Capsaicin (Nonivamide) is a high-purity capsaicinoid used for controlled pungency, irritation, and sensory activation. Chemically identical in function to natural capsaicin, nonivamide delivers reliable heat, TRPV1 receptor activation, and long-term stability, making it ideal for research, industrial formulations, repellents, sensory testing, and specialty products.

Product Specifications

Product details:

HL-Synthetic Capsaicin (CAS 2444-46-4), also known as Nonivamide or n-Vanillylnonanamide (PAVA), is a synthetic analog of capsaicin — the compound responsible for the heat of chili peppers. Unlike plant-derived capsaicin, nonivamide offers high purity, consistent potency, and superior stability, making it ideal for industrial, laboratory, and formulation use.

This material activates the TRPV1 pain and heat receptors, producing a strong burning sensation even at extremely low concentrations. Because of its predictable performance and long shelf life, nonivamide is widely used in repellents, sensory agents, topical research, defense products, flavor simulation, and chemical testing.

HL-Synthetic Capsaicin is supplied as a fine white to off-white crystalline powder with a minimum purity of > 98%, suitable for precise dosing and formulation.

Common Applications:

• Animal repellents & aversive coatings
• Pepper spray and defense formulations
• Sensory and irritation testing
• Research & laboratory use
• Pungency and heat simulation
• Pharmaceutical and cosmetic R&D

Why Use Nonivamide Instead of Natural Capsaicin?

• • Higher purity
  • More consistent potency
  • Better shelf stability
  • Easier formulation
  • No agricultural variability

Caution:

Capsaicin is a chemical irritant that can produce a sensation of burning in any tissue it comes into contact with. It is for laboratory research and industrial use only. Handle with care and follow proper safety protocols.
