Eye Contact: Rinse eyes gently with lukewarm water for 10-15 minutes; seek medical attention if redness or discomfort continues
Skin Contact: Remove contaminated clothing, wash affected area with mild soap and running water; persistent irritation calls for medical evaluation
Inhalation: Go to area with fresh air; seek medical help if coughing or breathing difficulty remains
Ingestion: Rinse mouth, drink a moderate amount of water; avoid inducing vomiting; call medical professionals if stomach pain or nausea occurs
General Advice: Show MSDS to physician in case of exposure; avoid handling material with bare hands
Suitable Extinguishing Media: Use carbon dioxide, dry chemical powder, or foam; water spray can be employed for large fires
Unsuitable Extinguishing Media: Strong jets of water may scatter powder
Hazardous Combustion Products: May emit carbon monoxide, carbon dioxide, nitrogen oxides, and indole derivatives during burning
Firefighting Procedures: Firefighters should wear self-contained breathing apparatus and full protective clothing
Explosion Data: Material does not possess explosive properties under normal storage and handling conditions
Special Firefighting Equipment: Gloves, goggles, and impervious gear to avoid skin contact with burning residues
Personal Precautions: Wear gloves, eye protection, and a dust mask; prevent the formation of airborne dust
Environmental Precautions: Avoid discharge of large volumes into surface water, drains, or soil
Methods for Cleaning Up: Scoop up spill using clean, dry tools; place in suitable disposal container; use a damp cloth to collect fine dust; ventilate affected area
Emergency Procedures: Restrict access during clean-up; inform safety personnel about the release
Safe Handling Advice: Minimize dust production; avoid direct contact with eyes, skin, and clothing; use in well-ventilated conditions; wash hands after use
Safe Storage Conditions: Store in tightly sealed container, kept dry and away from light; room temperature between 15-25°C to preserve stability
Incompatibilities: Strong oxidizing agents, strong acids and bases
Storage Class: Chemical storage—organic solids
Occupational Exposure Limits: No established exposure limits specific to Indole-3-Lactic Acid
Engineering Controls: Local exhaust ventilation at point of dust generation
Personal Protective Equipment: Laboratory coat, nitrile gloves, safety goggles, dust mask (if ventilation insufficient)
Hygiene Measures: Wash hands and exposed skin after handling; remove contaminated clothing promptly
Respiratory Protection: Use dust mask if handling large quantities without adequate ventilation
Eye Protection: Safety glasses with side shields

Appearance: Off-white to pale beige powder or crystalline solid
Odor: Slight, characteristic odor of indole derivatives
pH: Approx. 2.5–3.5 (1% aqueous solution)
Melting Point: 175–180°C
Boiling Point: Not applicable (decomposes before boiling)
Solubility: Slightly soluble in water, freely soluble in ethanol and DMSO
Vapor Pressure: Negligible
Density: Around 1.36 g/cm³
Partition coefficient (log Kow): Data not widely available; expect low mobility in water
Flash Point: Not known to be flammable in ordinary use
Auto-Ignition Temperature: Data not confirmed
Viscosity: Not applicable for solid
Chemical Stability: Stable under recommended storage and handling conditions
Thermal Decomposition: Begins above 180°C, emitting acrid fumes
Conditions to Avoid: Strong heat, open flames, excessive moisture, direct sunlight
Materials to Avoid: Strong oxidizing agents, strong acids or alkalis
Hazardous Decomposition: Carbon oxides, nitrogen oxides, potentially indole or other aromatic fragments
Polymerization: No hazardous polymerization expected
Acute Toxicity: Oral LD50 not well established in humans or animals due to limited exposure data; presumed low toxicity based on structure and analogs
Skin Corrosion/Irritation: May cause mild redness on sensitive skin
Eye Damage/Irritation: Short-term irritation possible if dust or solution enters eye
Inhalation Exposure: Dust inhalation may trigger coughing or sneezing
Ingestion Effects: Mild gastrointestinal discomfort—nausea, abdominal pain
Chronic Effects: No data on carcinogenic, reproductive, or mutagenic risks; routine handling has not been linked with adverse health outcomes in lab use
Sensitization: No reports of allergic skin reactions
Medical Conditions Aggravated by Exposure: People with preexisting respiratory issues may experience discomfort after inhaling dust
Ecotoxicity: Not expected to disrupt aquatic life at low concentrations, based on its biochemical similarity to naturally occurring indole compounds
Aquatic Toxicity: Data lacking for fish, daphnia, algae; anticipated low toxicity due to rapid degradation and low solubility
Persistence and Degradability: Likely to degrade in soil and water by microbial action; may persist briefly in environments lacking microorganism activity
Bioaccumulative Potential: No significant bioaccumulation predicted
Mobility in Soil: Limited mobility; compound will adsorb to soil particles
Other Adverse Effects: No ozone depleting or endocrine-disrupting properties identified
Waste Treatment Methods: Small sample amounts can be dissolved in water and disposed through laboratory drains in accordance with local requirements; large quantities may require hazardous waste handling
