Toluene 99.5% or Methylbenzene or Phenylmethane
Product Overview & Quality
- Product Name: Toluene 99.5% or Methylbenzene or Phenylmethane
- Brand: QReC (Product Code: QR-T5031-1-2501)
- Grade: Analytical Reagent (AR Grade) featuring a certified chemical purity of 99.5 percent or higher. Manufactured and distilled under strict QReC global laboratory standards. Rigorously regulated to maintain exceptionally low ppm thresholds of evaporation residue, sulfur compounds, moisture content, free benzene, and trace heavy metals. This premium aromatic solvent profile prevents baseline interference in spectrophotometric and chromatographic analyses and ensures reproducible reaction yields. Packaged in a heavy-duty amber glass bottle for maximum chemical integrity and light protection.
- Physical Properties: Clear, colorless, highly mobile liquid with a characteristic sweet, pungent aromatic hydrocarbon odor. Volatile and flammable liquid and vapor with a low flash point; vapors are heavier than air and can flow across ground surfaces to distant ignition points.
- Solubility: Insoluble and immiscible with water (floats as a distinct upper layer due to lower density); completely miscible in all proportions with common organic solvents including absolute ethanol, acetone, diethyl ether, and chloroform; high solvency for non-polar oils, resins, waxes, and fats.
- Key Use: Heavily utilized as an essential aromatic non-polar solvent for extracting and isolating active natural compounds, resins, and organic substances in analytical and research laboratories. Widely applied as a classic reaction medium and versatile synthetic precursor in organic chemical synthesis (often preferred over benzene due to its higher boiling point around 110 degrees Celsius and lower relative volatility). Serves as an effective clearing and de-waxing agent in histology and pathology tissue preparation. Frequently used as a mobile phase component or eluent modifier in thin-layer chromatography (TLC) and column chromatography, and commonly applied in polymer, paint, rubber, and adhesive material testing.
Safety & Hazards (Critical, Flammable, Reproductive Toxicity & Neurotoxic)
- Classification: Highly flammable liquid and vapor. May be fatal if swallowed and enters airways. Causes skin irritation. May cause drowsiness or dizziness. Suspected of damaging the unborn child. May cause damage to organs (Central nervous system) through prolonged or repeated exposure.
- Health Risks: Direct eye contact triggers stinging irritation, conjunctival redness, and tearing. Dermal exposure rapidly dissolves natural protective skin lipids, leading to erythema, cracking, and localized dermatitis. Inhalation of concentrated vapors violently depresses the central nervous system, inducing headaches, dizziness, nausea, lightheadedness, loss of coordination, memory deficits, or unconsciousness; chronic vapor inhalation is definitively linked to neurotoxicity and hearing damage. Ingestion followed by chemical aspiration into the respiratory tract induces destructive, potentially fatal chemical pneumonitis and acute pulmonary edema.
- First Aid Measures: Immediately flush affected eyes or skin with plenty of continuous flowing clean water for at least 15 minutes while stripping contaminated clothing. In case of inhalation, rapidly transfer the individual to fresh air. If accidentally swallowed, do NOT induce vomiting due to severe pulmonary aspiration hazards; seek immediate, urgent emergency medical attention.
Handling & Storage
- Storage: Highly Flammable and Neurotoxic Aromatic Solvent. Low flash point creates elevated fire hazards; vapors easily form explosive air mixtures. Must be preserved in its original, tightly sealed QReC amber glass bottle inside an approved flammable liquid safety cabinet. Store in a cool, dry, and excellently ventilated chemical warehouse or storage room at stable room temperature (below 30 degrees Celsius), sheltered from direct sunlight. Keep strictly segregated from open flames, sparks, hot surfaces, static electrical discharge, and strong oxidizing agents.
- Precautions: Standard specialized PPE is mandatory, including solvent-resistant gloves (thick nitrile or Viton), splash-proof safety goggles, and a protective lab coat. Handle exclusively and strictly within a properly functioning laboratory fume hood to prevent vapor inhalation and eliminate flammable vapor accumulation. Ground and bond containers during volume transfers to avoid static ignition.
