Cleanup methods: Sweep up with minimal dust generation, use damp absorbent material if necessary, place in suitable well-labeled container for disposal
Decontamination: Wash area with water after removal of residues

7. Handling and Storage

Safe handling advice: Handle in a well-ventilated place, avoid direct contact with eyes, skin, and clothing, keep containers tightly closed
Hygiene measures: Wash hands after use, do not eat, drink, or smoke in work area, remove contaminated clothing
Storage conditions: Keep in cool, dry, well-ventilated area away from incompatible materials, store in original packaging
Storage temperature: Room temperature (15–25°C) is preferred
Incompatibilities: Strong oxidizers, strong acids, strong bases

8. Exposure Controls and Personal Protection

Occupational exposure limits: No established exposure limits
Engineering controls: Use with local exhaust ventilation or in chemical fume hood to avoid airborne dust
Eye/face protection: Chemical splash goggles
Skin protection: Nitrile or latex gloves, laboratory coat
Respiratory protection: Use dust mask if ventilation is poor or risk of airborne exposure exists
Other protection: Eye wash stations and safety showers should be accessible

9. Physical and Chemical Properties

Appearance: White or off-white powder
Odor: Odorless or faint organic odor
pH: Not available (typically acidic in aqueous solution)
Melting point: 153–156°C (as reported in literature)

Partition coefficient (log Kow): Not determined

10. Stability and Reactivity

Chemical stability: Stable under recommended storage conditions, no decomposition under normal use
Reactivity: Does not react rapidly with water or air under ambient conditions
Hazardous reactions: May react with strong oxidizers, risk of exothermic reaction not significant under standard laboratory use
Decomposition products: Carbon monoxide, carbon dioxide, other carbon oxides if heated to decomposition
Conditions to avoid: Moisture, excessive heat, incompatible substances (oxidizers, acids, bases)

11. Toxicological Information

Acute toxicity: No official data, limited animal or human exposure information
Irritation: Can cause mild skin and eye irritation based on structure and analogs
Sensitization: Not classified as sensitizer, minimal reports of allergic response
Chronic effects: No long-term toxicity studies available, prolonged exposure not recommended
Carcinogenicity: Not listed as carcinogen by NTP, IARC, or OSHA
Mutagenicity / Reproductive toxicity: No data currently available, handle with care
Routes of exposure: Inhalation, ingestion, skin, and eye contact

12. Ecological Information

Aquatic toxicity: No specific data, general good chemical handling practice suggests avoiding release to the environment
Persistence and degradability: Not expected to persist or bioaccumulate significantly, degrades under environmental conditions
Bioaccumulation potential: No evidence of bioaccumulation
Mobility in soil: Not measured; water solubility suggests limited soil movement
Other adverse effects: No classification as environmentally hazardous under current regulations

13. Disposal Considerations

Waste treatment methods: Dispose of in accordance with local, regional, and national laws
Waste container: Use properly labeled, sealed containers
Disposal restrictions: Do not discharge into surface water, drains, or the environment
Additional information: Contaminated packaging should be treated as chemical waste
