FAQ

What is Indoleacetic Acid (CAS: 87-51-4)?

Indoleacetic Acid (IAA), CAS 87-51-4, is a naturally occurring plant hormone belonging to the auxin family. Its chemical formula is C10H9NO2. IAA regulates growth, cell elongation, and root development in plants. It is a colorless solid with a faint odor, soluble in water and alcohol. Commonly used in agriculture and research, IAA plays a key role in plant physiology and is a critical compound in studying phytohormonal effects.

What are the main uses of Indoleacetic Acid (CAS: 87-51-4)?

Indoleacetic Acid (IAA, CAS 87-51-4) is widely used in agriculture as a growth regulator to enhance plant development and fruit set. In pharmaceuticals, it serves as a precursor for drug synthesis. It also finds applications in biotechnology for plant tissue culture and in research for studying auxin signaling. IAA is essential in understanding plant responses to environmental stress and is a key component in horticultural treatments.

Is Indoleacetic Acid (CAS: 87-51-4) safe?

Indoleacetic Acid (IAA, CAS 87-51-4) is generally safe when used properly, but it may cause skin or eye irritation upon contact. Ingestion or inhalation of high concentrations can pose health risks. Safety guidelines recommend wearing gloves, goggles, and ensuring adequate ventilation. It should be handled with care, following OSHA and EPA standards. Always refer to the Safety Data Sheet (SDS) for specific precautions.

How should Indoleacetic Acid (CAS: 87-51-4) be stored?

Indoleacetic Acid (IAA, CAS 87-51-4) should be stored in a cool, dry, and dark place to maintain stability. Keep it sealed in airtight, light-resistant containers to prevent degradation. Avoid exposure to moisture and high temperatures. Store in a well-ventilated area, away from incompatible substances. Proper storage ensures longevity and safety, as recommended by chemical storage guidelines.
