Product Name: C8-C20 Alkane Standard Solution
Chemical Family: Aliphatic hydrocarbons
Common Uses: Laboratory reference material, calibration for chromatographic analysis
Physical State: Liquid mixture
Odor: Mild, reminiscent of gasoline or lighter fluid
Color: Clear to pale yellow
Hazard Classifications: Flammable liquid, health hazard through inhalation, skin and eye irritant
Signal Word: Warning
Main Hazards: Rapid evaporation leads to vapor buildup, flammable atmosphere risk, prolonged exposure can cause headaches or dizziness, and skin contact may dry out or irritate
Symptoms of Overexposure: Drowsiness, respiratory discomfort, nausea, and skin redness or dryness
Main Ingredients: n-octane (C8), n-nonane (C9), n-decane (C10), n-undecane (C11), n-dodecane (C12), n-tridecane (C13), n-tetradecane (C14), n-pentadecane (C15), n-hexadecane (C16), n-heptadecane (C17), n-octadecane (C18), n-nonadecane (C19), n-eicosane (C20), all in a hydrocarbon solvent base
Concentration Range: Usually 1000 ppm to 5000 ppm per individual alkane in a carrier solvent
CAS Numbers: Each alkane has its own; for example, octane: 111-65-9, nonane: 111-84-2, decane: 124-18-5, and so forth
Impurities: Less than 0.1% total, primarily other trace alkanes or residual solvents
Inhalation: Move person to fresh air; if symptoms linger, seek medical attention
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and water
Eye Contact: Rinse gently with clean water for several minutes; remove contact lenses if present and easy to do
Ingestion: Seek medical help; do not induce vomiting unless instructed by a healthcare provider
Note: Fatigue and inhalation risks are much higher indoors or in poorly ventilated labs—open doors and windows where possible
Extinguishing Media: Foam, dry powder, or carbon dioxide preferred, water spray for cooling containers only
Specific Hazards: Vapors form explosive mixtures with air, fire can flash back along vapor trail
Protective Gear: Full turnout gear and self-contained breathing apparatus
Hazardous By-products: Fumes may include carbon monoxide, carbon dioxide, and other potentially toxic compounds
Spill Containment: Eliminate all ignition sources, ventilate area
Personal Protection: Gloves, chemical splash goggles, and protective apron
Methods for Clean-up: Use absorbent material such as sand or vermiculite, collect waste in sealable containers
Environmental Precautions: Prevent material from entering drains or watercourses; spills travel quickly over hard surfaces and can form vapor clouds if left unchecked
Handling: Work in well-ventilated space, keep away from sparks, flames, static electricity
Storage Conditions: Store in tightly sealed containers in a cool, dry, well-ventilated location, away from direct sunlight and sources of heat
Incompatibilities: Strong oxidizers, acids, or sources of ignition
Special Notes: Even small spills can cause slick surfaces and dangerous vapors; always close container lids tightly after use
Engineering Controls: Fume hood or local exhaust recommended
Personal Protection Equipment: Nitrile or neoprene gloves, safety goggles, flame-retardant lab coat
Respiratory Protection: Use NIOSH-approved organic vapor respirator if ventilation inadequate
Hygiene Measures: Wash hands before breaks and after finishing work, avoid eating and drinking in the workspace
Boiling Range: Around 125°C to 343°C, depending on alkane chain length
Flash Point: Commonly between 23°C and 75°C; shorter chains ignite at lower temperatures
Vapor Pressure: Falls as chain length increases; higher for C8, lower for C20
Density: From 0.7 to 0.8 g/cm³
Solubility in Water: Negligible
Other Notable Properties: Highly mobile on flat surfaces, vaporizes slowly but completely in open air given time
Chemical Stability: Stable under normal conditions if kept cool and away from reactive substances
Reactivity: May react vigorously with strong oxidizers
Hazardous Decomposition Products: Generates carbon oxides, sometimes aldehydes; conditions such as fire or strong acid can speed up breakdown
Routes of Exposure: Inhalation, skin absorption, incidental ingestion
Acute Effects: Headache, dizziness, skin dryness, nausea
Chronic Effects: Prolonged or repeated contact may cause dermatitis or aggravate existing respiratory conditions
Sensitization: Not typically reported, but vulnerable individuals may be more sensitive to vapor exposure
Carcinogenicity: Alkanes in this range not classified as carcinogens under general regulatory guidance
Persistence and Degradability: Alkanes tend to persist in the environment, degrade slowly
Mobility in Soil: High for light members of the group, low for heavier ones
Aquatic Toxicity: Can be toxic to aquatic organisms, especially with chronic exposure
Bioaccumulation Potential: Mainly a risk for marine organisms if substances reach waterways
Waste Disposal: Treat as hazardous waste, collect and send for disposal at permitted facility
Contaminated Packaging: Triple rinse empty containers before recycling, or dispose with hazardous chemical waste
Legal Restrictions: No pouring down the drain, no casual evaporation into open air; labs managing organic solvents have a responsibility to track and control all hazardous waste streams
UN Number: UN1993 (for flammable liquid, n.o.s., may cover many hydrocarbon mixtures of this type)
Shipping Class: Flammable liquid, packed in certified, sealed containers
Precautionary Statements: Avoid rough handling, keep upright during transport, keep away from heat and sunlight
Labelling: Use clear flammable labels and ensure documentation matches container content
Global Regulations: Classified under most chemical safety standards (GHS, OSHA, EU CLP) as a flammable liquid
Workplace Exposure Limits: Limits set for hydrocarbon mixtures and individual compounds by agencies like OSHA and ACGIH, with the focus usually on controlling inhalation exposure
Environmental Release: Many countries require reporting if significant volumes are spilled or released
Lab Safety Rules: Users must receive chemical safety training and follow institutional chemical hygiene plans designed to minimize exposure and contain any mishaps immediately
