Indole-3-acetic acid is a white crystalline solid with a characteristic odor resembling that of tryptophan. Its appearance is that of fine powder or small crystals.
The molar mass of Indole-3-acetic acid is 175.19 g/mol, and its density is approximately 1.264 g/cm³. In comparison to common household items, Indole-3-acetic acid has a lower molar mass than glucose (180.16 g/mol) but higher density than water (1 g/cm³).
The melting point of Indole-3-acetic acid is around 168-170°C, while its boiling point is approximately 253-254°C. In terms of melting point and boiling point, Indole-3-acetic acid has a higher melting point than butter (32-35°C) and a lower boiling point than vinegar (100°C).
Indole-3-acetic acid is sparingly soluble in water, and its viscosity is relatively low. In comparison to common household items, it is less soluble in water than salt but more soluble than oil. Its viscosity is similar to that of vinegar.
🏭 Production & Procurement
Indole-3-acetic acid is primarily produced in plants through the tryptophan-dependent biosynthetic pathway. This pathway involves several enzymatic reactions that ultimately convert tryptophan into Indole-3-acetic acid, which serves as a key plant hormone responsible for regulating growth and development.
Indole-3-acetic acid can also be procured through chemical synthesis or fermentation processes. Chemical synthesis involves the conversion of tryptophan or other precursor molecules into Indole-3-acetic acid using various chemical reactions. On the other hand, fermentation processes typically involve the use of microorganisms such as bacteria or fungi to produce Indole-3-acetic acid in large quantities for commercial purposes.
Once produced, Indole-3-acetic acid can be transported in a variety of ways depending on the intended application. In plants, Indole-3-acetic acid is transported from cell to cell through specialized transport proteins or by diffusion. For commercial purposes, Indole-3-acetic acid can be transported in liquid form or as a powder, often packaged and shipped in containers to ensure stability and purity during transit.
⚠️ Safety Considerations
Safety considerations for Indole-3-acetic acid include the potential for skin and eye irritation upon contact. It is important to handle this substance with care, wearing appropriate personal protective equipment such as gloves and safety goggles. Indole-3-acetic acid should be stored in a cool, dry place away from sources of heat or ignition to prevent any risk of fire or explosion.
Indole-3-acetic acid, also known as IAA, is a naturally occurring plant hormone that plays a crucial role in regulating plant growth and development. It acts as a signaling molecule, influencing processes such as cell elongation, root initiation, and fruit development. IAA is involved in tropic responses to light and gravity, as well as in the formation of adventitious roots. Understanding the pharmacology of Indole-3-acetic acid is essential for researchers studying plant physiology and agriculture.
Hazard statements for Indole-3-acetic acid include its potential to cause skin and eye irritation, as well as respiratory irritation if inhaled. It may also be harmful if swallowed. Indole-3-acetic acid should be used in a well-ventilated area to minimize exposure, and any spills should be cleaned up promptly to prevent further contact. It is advisable to handle this substance with caution and to follow proper safety protocols to avoid any adverse effects.
Precautionary statements for Indole-3-acetic acid include recommendations to wear protective clothing, gloves, and eye/face protection when handling this substance. It is important to wash hands thoroughly after handling and to avoid breathing in any vapors or mists. In case of skin contact, the affected area should be washed with soap and water, and in case of eye contact, the eyes should be rinsed carefully with water for several minutes. Indole-3-acetic acid should be used in a laboratory setting with appropriate safety measures in place to minimize the risk of exposure.
