Intended Use: Laboratory reagent, ion-pairing reagent in HPLC
Manufacturer: Consult supplier label
Emergency Contact Number: Refer to local poison control center or Chemtrec for emergencies associated with exposure
Hazard Classification: Not classified as hazardous according to OSHA GHS criteria, but dust can cause irritation
Label Elements: No pictograms needed for GHS, but prudent laboratory practice calls for minimizing contact
Physical Hazards: White crystalline powder, not especially flammable or reactive under normal conditions
Health Hazards: Potential for eye, skin, and respiratory tract irritation from dust exposure
Environmental Hazards: Not expected to present significant hazards, but avoid release to waterways
Precautionary Statement: Handle in well-ventilated environments with common-sense laboratory protective gear
Chemical Identity: 1-Butanesulfonic Acid Sodium Salt
Percent by Weight: >98% pure
Impurities: Trace impurities may include unreacted starting materials and moisture, often less than 2%
Eye Contact: Immediately flush eyes with running water for at least 15 minutes, remove contact lenses, continue rinsing, seek medical attention if irritation remains
Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing, medical advice if rash or discomfort develops
Inhalation: Remove person to fresh air, support respiration, consult medical professional if symptoms persist
Ingestion: Rinse mouth with water, do not induce vomiting unless advised by poison control, seek prompt medical help
Symptoms: Irritation, coughing, mild discomfort in eyes or on skin; serious effects are unlikely in typical exposures
Suitable Extinguishing Media: Use water spray, dry chemical, carbon dioxide, or foam as needed
Hazards from Combustion: Product may decompose producing sulfur oxides and sodium oxides when heated strongly
Protective Equipment: Standard firefighting gear including self-contained breathing apparatus to prevent inhaling smoke and fumes
Specific Firefighting Methods: Move containers from fire area if possible without risk, cool unopened containers, avoid water runoff into drains
Personal Precautions: Wear dust mask, goggles, gloves, and laboratory coat; avoid generating dust clouds
Environmental Precautions: Prevent large amounts entering waterways, soil, or sewer systems, clean up promptly
Methods for Cleaning Up: Scoop up material with clean, dry tools, place in suitable container for disposal, ventilate area, wash area with water after pickup is complete, avoid sweeping dry product to limit dust; use wet methods if possible
Handling Guidelines: Handle using standard laboratory hygiene, avoid inhalation and direct contact with skin or eyes, work in well-ventilated area, wash thoroughly after use
Storage Conditions: Store in tightly closed containers, keep in cool, dry, well-ventilated place, segregate from strong oxidizers and acids, protect from moisture and humidity, retain product in original or chemical-resistant packaging, label containers with proper identification
Occupational Exposure Limits: Not established by OSHA, ACGIH, or other regulatory bodies; treat as nuisance dust with recommended threshold of 10 mg/m³ total particulate
Engineering Controls: Use local exhaust ventilation to minimize dust accumulation in air
Personal Protective Equipment: Safety goggles or glasses with side shields, chemical-resistant gloves (nitrile or latex), laboratory coat, dust respirator in poorly ventilated settings, always have eyewash station and safety shower accessible

Chronic Effects: Not identified in research literature
Carcinogenicity: Not classified as a carcinogen by IARC or other agencies
Sensitization: No reports as a skin or respiratory sensitizer
Ecotoxicity: Not known to be highly toxic to aquatic organisms at low concentrations, but best practice avoids spillage into waterways
Persistence and Degradability: Inorganic salts like this typically remain stable unless neutralized or biologically degraded over long periods
Bioaccumulation Potential: Product is not likely to concentrate in the tissues of living organisms
Mobility: High in water due to good solubility, may spread quickly in soil
Other Adverse Effects: Always limit unnecessary releases, especially in sensitive locations
Safe Disposal Methods: Place in sealed container for chemical waste disposal, do not dispose in regular trash or via drain. Use licensed chemical disposal vendor or follow guidelines from environmental authorities. Rinse contaminated packaging thoroughly before recycling or disposal, avoid mixing with incompatible substances
