Substance: Fingolimod Hydrochloride
Synonyms: FTY720, Gilenya
Drug Class: Sphingosine 1-phosphate receptor modulator
Appearance: White to off-white crystalline solid
Common Use: Treatment of relapsing-remitting multiple sclerosis
Classification: Not considered a hazardous substance under typical handling conditions
Acute Effects: Can affect heart rate and immune system if ingested or inhaled
Health Risks: May cause respiratory irritation, headache, or dizziness if dust is inhaled; harmful if swallowed
Warning Signs: Seek medical supervision for exposure linked to symptoms beyond mild irritation
Chemical Identity: Fingolimod Hydrochloride (C19H33NO2•HCl)
Active Component: Fingolimod base, hydrochloride salt form; no major inactive ingredients at pure substance stage
Purity: Pharmaceutical-grade material
Inhalation: Move to fresh air, seek medical attention if symptoms persist
Skin Contact: Wash with soap and water, remove contaminated clothing
Eye Contact: Rinse cautiously under running water for several minutes, remove contact lenses if present
Ingestion: Rinse mouth, obtain medical advice immediately; possible adverse effects on heart rhythm demand prompt evaluation
Suitable Extinguishing Agents: Water spray, foam, dry chemical, carbon dioxide
Specific Hazards: Thermal decomposition may release toxic fumes including nitrogen oxides and hydrogen chloride gas
Protective Equipment: Full protective gear, self-contained breathing apparatus
Fire Response: Limit smoke exposure and avoid breathing combustion products
Personal Protection: Use disposable gloves, laboratory coat, dust respirator if powder is present
Environmental Precautions: Prevent entry to sewers or waterways
Spill Clean-up: Sweep into labeled chemical waste container, moisten powder to avoid dust generation
Ventilation: Ensure adequate air movement during clean-up
Handling: Minimize dust production, avoid contact with eyes and skin, use in a chemical fume hood
Storage: Store in tightly sealed containers, away from direct sunlight, moisture, and incompatible materials
Stability: Maintain at controlled room temperature; follow pharmaceutical stability guidelines
Engineering Controls: Operate within properly vented areas, use safety cabinets for high-quantity manipulation
Personal Protective Equipment: Protective gloves, safety goggles, lab coat; respiratory protection in case of accidental dust
Hygiene Practices: Wash hands before breaks and after handling the compound
Exposure Limits: No established occupational exposure limit; minimize exposure through best laboratory practice
Physical State: Solid
Color: White to off-white
Melting Point: Reports indicate range near 102–104°C
Solubility: Soluble in water and organic solvents such as methanol and ethanol
Odor: Odorless
Molecular Weight: Approximately 343 g/mol (hydrochloride form)
Chemical Stability: Stable under normal storage conditions
Hazardous Reactions: None expected under standard handling; avoid strong acids, bases, and oxidizers
Decomposition Products: Thermal breakdown yields nitrogen oxides, carbon oxides, hydrochloric acid fumes
Absorption: Significant risk primarily from ingestion rather than skin or eye absorption
Acute Effects: Central nervous system and cardiac effects; bradycardia, headache, dizziness possible
Chronic Effects: Prolonged exposure studies limited; professional pharmaceutical use focuses on avoiding unnecessary exposure
Carcinogenicity: No adequate data to designate as carcinogen
Sensitization: No clear evidence of skin or respiratory sensitization in available medical literature
Ecotoxicity: Not expected to pose significant environmental risk in normal quantities; large-scale spills require evaluation
Persistence and Degradability: Data limited; breakdown pathways in sewage or soil unclear
Bioaccumulation: No indication of significant bioaccumulation potential
Aquatic Impact: Precaution against waterway discharge based on pharmaceutical best practice
Waste Disposal: Dispose in accordance with local and national regulations for pharmaceutical waste
Incineration: Suitable option at authorized facility
Avoid: Flushing into drains or regular trash disposal; specialized containers ensure responsible end-of-life handling
Shipping Classification: Not regulated for transport in small laboratory quantities under common guidelines
Packaging: Leak-proof, clearly labeled containers; follow typical protocols for pharmaceutical raw materials
Transportation Precautions: Prevent breakage, release, or contamination during transit
Pharmaceutical Regulation: Subject to prescription control in many countries
Workplace Safety: Covered under general chemical handling rules; no unique national hazards assigned
GHS Labelling: Health hazard icon where pure substance handled routinely
OSHA/WHMIS/CLP: Not specifically listed; local occupational health agencies can provide more detailed guidance
