Chemical Name: Strontium Chloride Hexahydrate
Common Names: Strontium dichloride, SrCl2·6H2O
Formula: SrCl2·6H2O
Appearance: White, odorless crystalline solid
Uses: Water treatment processes, pyrotechnics, research labs, dental toothpaste ingredient, sometimes a supplement for aquarium life
Smell: Odorless
Taste: Saline, bitter
Synonyms: None in typical circulation beyond listed names.
GHS Classification: Eye Irritation (Category 2A), Skin Irritation (Category 2), Acute Toxicity Oral (Category 4)
Label Elements: Exclamation mark symbol
Routes of Exposure: Inhalation, skin, eye, ingestion
Health Risks: Irritation to eyes, skin, mucous membranes; nausea, vomiting, or diarrhea after significant exposure; potential for more serious outcomes in pre-existing health issues
Environmental Risks: Not especially bioaccumulating, yet spills and waste matter can disturb aquatic habitats, particularly in closed systems
Chemical: Strontium Chloride Hexahydrate
CAS Number: 10025-70-4
Concentration: More than 98% for lab-grade material
Impurities: Trace elements mostly irrelevant to routine safety, but may rarely contain calcium or magnesium contaminants
Eye Contact: Rinse with water for at least 15 minutes, keeping eyelids separated; seek medical evaluation if irritation lingers
Skin Contact: Wash area thoroughly under running water, remove contaminated clothes, talk to a doctor if redness or itching continues
Inhalation: Move to fresh air, loosen clothing; if breathing problems stick around, get medical help
Ingestion: Rinse mouth, don’t force vomiting, see doctor for strong symptoms — especially on large intake
Flammability: Nonflammable, but may emit toxic fumes if heated above decomposition point
Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Combustion Products: Hydrogen chloride gas, strontium oxides
Protective Equipment: Proper firefighting gear, full SCBA in enclosed spaces
Special Procedure: Cool containers near fire with water mist
Personal Protection: Gloves, goggles, dust mask for large spills
Cleanup Methods: Scoop spilled material, avoid raising dust, ventilate area well, wipe residues with wet absorbent material, avoid direct drains to effluent
Environmental Precautions: Prevent from reaching soil or groundwater; don’t flush down toilets or sinks
Safe Handling: Practice careful transfer, use personal protective equipment if spill or splash possible, avoid breathing dust or vapors
Storage Needs: Airtight containers, cool and dry places away from heat; label all containers clearly; keep out of reach of untrained personnel
Incompatibles: Reacts with strong acids, oxidizing agents; excessive moisture degrades the product
Engineering Controls: Local exhaust preferred for dusty or moist work, ensure proper general ventilation at all times
Protective Gear: Chemical goggles, nitrile or latex gloves, lab coat or apron for regular use, closed-toed shoes in work zones
Respiratory Protection: Dust mask required if handling large quantities or during cleanup
Hygiene Tips: Wash hands before eating, drinking, or touching face; change out of contaminated clothes after handling
Appearance: White crystalline solid, sometimes clumped by absorbed water
Solubility: High in water, forming clear solutions
Melting Point: Decomposes before melting, above 61°C for hexahydrate
Odor: None
Boiling Point: Not applicable (loses water, then decomposes)
pH (aqueous): Near neutral, slightly acidic
Vapor Pressure: Insignificant
Bulk Density: Moderate, easy pouring unless compacted
Chemical Stability: Stable under recommended storage conditions; prolonged air exposure encourages absorption of moisture
Reactivity Profile: No major red flags under normal chemistry practice; heat or acid contact triggers decomposition
Hazardous Decomposition: Hydrogen chloride gas, strontium oxide
Polymerization Risk: None
Incompatibles: Strong acids and oxidizers accelerate breakdown, damp conditions spoil the solid
Routes of Entry: Ingested, inhaled, skin or eye contact
Acute Symptoms: Nausea, abdominal pain, mild irritation, cramping
Irritation: Possible for sensitive skin or eyes; more pronounced in concentrated solution
Chronic Exposure: Uncommon in daily lab use, but repeated high doses cause issues with calcium metabolism in animal studies
Carcinogenicity: Not classified as a carcinogen by IARC, NTP, or OSHA
Aquatic Toxicity: Modest concern, excess levels can harm aquatic invertebrates
Persistence: Dissolves and disperses quickly in water; easily diluted with large water volumes
Mobility in Soil: Highly mobile if spilt, risk of contaminating groundwater in bulk spill scenarios
Bioaccumulation: Low to negligible under normal use
Waste Treatment: Collect and hand over to qualified chemical waste company; avoid landfill disposal or pouring into sewage systems
Container Disposal: Rinse, deface label, and follow local hazardous materials laws
Regulatory Instructions: Stick to regional, national, or community guidelines on chemical waste, don’t improvise
UN Number: Not regulated for most standard shipping
Proper Shipping Name: Strontium Chloride Hexahydrate
Hazard Classification: Not typically classed as a hazardous material during routine transit
Packing Group: Not assigned
Environmental Hazards: Avoid bulk spills during loading and unloading
OSHA Status: Not specifically regulated but falls under general chemical hygiene plans
SARA Title III: Not listed under critical sections
California Prop 65: Not cited as a listed substance
TSCA Status: Included in chemical inventory
Other Local Rules: Depending on region, always verify local guidelines for workplace labeling and community right-to-know programs
