CAS No.: 61788-71-2
Synonyms / IUPAC Name: Di(propylene glycol) phenyl ether; Phenoxy dipropylene glycol ether
Molecular Formula: C₁₂H₁₈O₃
Molecular Weight: ~210 g/mol
Appearance: Colourless to pale yellow clear liquid

Physicochemical Properties (Typical)

• Boiling Point: ≈ 280 °C
• Density: ~1.05 g/cm³ at 20 °C
• Refractive Index: ~1.579 (n²⁰ᴰ)
• Solubility in Water: Very low; predominantly hydrophobic
• Vapour Pressure: Low (slow-evaporating glycol ether)
• Other Notes: Low volatility and strong solvency for high-performance applications

Purity & Quality Standards

• Typical Purity: ≥ 98% (by GC or appropriate assay)
• Appearance: Clear liquid, free of visible particulates or haze
• Specification Indicators: Assay, moisture content, acid value, density and refractive index controlled to specification
• Storage Recommendation: Store sealed in a cool (<30 °C), dry and well-ventilated area; protect from strong oxidisers and excessive heat

Applications / Uses

• Slow-evaporating solvent in coatings, inks, adhesives and resin systems
• High-solvency component for cleaning and surface-treatment formulations
• Coupling solvent and intermediate in specialty chemical processes
• Suitable for formulations requiring low volatility, strong wetting and good leveling performance

Safety & Handling

• Flammability: Combustible liquid; vapours may form flammable mixtures under certain conditions.
• Health Hazards:
• Inhalation: May cause respiratory irritation or dizziness at high vapour concentrations.
• Skin Contact: Prolonged or repeated contact may cause mild irritation.
• Eye Contact: May cause eye irritation.
• Precautions:
• Use only in well-ventilated areas or with local exhaust ventilation.
• Wear suitable protective gloves, eye/face protection and protective clothing.
• Avoid ignition sources, heat, sparks and static; ground/bond containers during transfer.
• Keep away from strong oxidising agents and extreme heat.
• Reactivity / Incompatibilities: Avoid strong oxidisers, strong acids and strong bases; decomposition may occur at elevated temperatures.
• First Aid (general guidance):
• Inhalation: Move to fresh air; seek medical attention if symptoms persist.
• Skin: Remove contaminated clothing and wash with soap and water.
• Eyes: Rinse cautiously with water for several minutes; seek medical help if irritation continues.
• Ingestion: Do not induce vomiting; obtain medical attention immediately.

Packaging & Storage

• Packaging: Supplied in sealed, solvent-compatible industrial containers (e.g., steel drums, IBCs) as per customer requirement.
• Storage Conditions: Store in a cool (<30 °C), dry, well-ventilated area, away from direct sunlight, heat and incompatible materials; keep containers tightly closed when not in use.
• Shelf Life: Stable under recommended storage conditions; inspect container integrity and product appearance before extended use.
• Transport: Follow applicable local and international regulations for combustible liquids and solvent shipments.
