Chemical Name: 4-Piperidone Monohydrate Hydrochloride Chemical Formula: C5H9NO · HCl · H2O Common Synonyms: 1-Piperidinone, Hydrate, Hydrochloride salt Appearance: White to off-white crystalline powder Odor: Odorless Intended Use: Research and laboratory applications
Hazard Class: Harmful if swallowed, irritant Main Risks: May cause respiratory and skin irritation, eye irritation, harm to organs by prolonged exposure Signal Words: Warning Symptoms: Eye redness, skin rash, sore throat, dizziness Pictograms: Exclamation mark (according to GHS labeling), indicating acute toxicity and irritant properties
Substance Name: 4-Piperidone Monohydrate Hydrochloride CAS Number: 40064-34-4 Purity: Typically greater than 98% Other Ingredients: Trace moisture associated with monohydrate form
Inhalation: Move to fresh air and get medical attention if symptoms persist Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing Eye Contact: Rinse carefully with water for several minutes, removing contact lenses if possible Ingestion: Rinse mouth, do not induce vomiting, seek medical care Severe Case Response: Call a doctor if any discomfort continues
Suitable Extinguishing Media: Water spray, dry chemical, foam, or carbon dioxide Hazardous Combustion Products: Possible release of nitrogen oxides, hydrogen chloride, carbon monoxide, carbon dioxide Protective Equipment: Full protective gear and self-contained breathing apparatus for fire personnel Fire Behavior: Non-flammable as a solid, but decomposition at high temperatures may release toxic vapors
Spill Response: Wear gloves, eye protection, and mask Clean-Up: Avoid raising dust, collect material with care, ventilate area Personal Precautions: Keep away from skin, eyes, and avoid inhalation Environmental Precautions: Prevent spillage into drains or water sources
Handling: Work in fume hood, avoid contact with eyes and skin, avoid dust formation Hygiene Measures: Wash hands thoroughly after handling Storage Conditions: Store in a tightly sealed container, away from heat, moisture, and incompatible materials Temperature Recommendations: Store at room temperature or cooler, keep in a dry, ventilated place
Respiratory Protection: Use NIOSH-approved respirators if dust is present Hand Protection: Chemical-resistant gloves Eye Protection: Safety goggles Skin Protection: Lab coat, long pants, closed footwear Engineering Controls: Laboratory fume hood recommended during manipulation
Physical State: Solid, crystalline Melting Point: Typically 195–200°C (decomposes) Solubility: Soluble in water Odor Threshold: Not detected due to odorless nature pH: Slightly acidic in solution Density: Not widely published
Stability: Stable under normal storage and usage conditions Reactivity: May react with strong oxidizing agents Decomposition: Produces toxic fumes of nitrogen oxides and hydrochloric acid if heated strongly Incompatibilities: Strong acids, bases, and oxidizers
Routes of Exposure: Inhalation, ingestion, skin, and eye contact Acute Effects: Irritation to mucous membranes, skin rash or itching, eye discomfort Chronic Effects: Data limited; long-term impact not fully understood Carcinogenicity: Not classified as carcinogenic by IARC, NTP, OSHA LD50 Value: Not broadly available; avoidance of direct exposure is essential
Aquatic Toxicity: Information limited; best practice to avoid environmental release Persistence and Degradability: Not established Bioaccumulative Potential: Not established Precaution: Treat waste as hazardous, avoid draining into water systems
