Product Description

Product Description

Basic Information

• Product Name: p-Methylbenzaldehyde (4-Methylbenzaldehyde)
• Chemical Formula: C8H8O
• Molar Mass: 120.15 g/mol
• CAS Number: 104-87-0

Physical and Chemical Properties

• Appearance:
  • Colorless to light yellow liquid at room temperature, with a strong, almond-like odor.
  • Hygroscopic (absorbs moisture slightly) and may oxidize to p-toluic acid (4-methylbenzoic acid) when exposed to air.
• Physical Constants:
  • Melting Point: -6.2°C
  • Boiling Point: 204-205°C (at 1 atm)
  • Density: 1.019 g/cm³ (20°C)
  • Solubility: Slightly soluble in water (0.3 g/100 mL at 20°C), miscible with organic solvents (ethanol, ether, benzene).
• Chemical Reactivity:
  • Aldehyde Group: Undergoes typical aldehyde reactions, such as oxidation, nucleophilic addition, and condensation.
    • Oxidation: Readily oxidized to p-toluic acid with oxidants like KMnO4 or chromic acid.
    • Reaction with Tollens' reagent: Forms a silver mirror (positive test for aldehydes).
  • Methyl Group: Can undergo halogenation (e.g., chlorination or bromination) under radical conditions.
  • Condensation Reactions:
    • With amines to form imines (Schiff bases).
    • With active methylene compounds (e.g., malonic ester) in Knoevenagel condensation.

Applications

• Flavor and Fragrance Industry:
  • As a key ingredient in almond, cherry, and floral scents for perfumes and cosmetics.
  • In food flavorings (e.g., bakery products, confectionery) to impart nutty or fruity notes (GRAS-listed in the U.S.).
• Pharmaceutical Intermediates:
  • Synthesis of drugs such as antihistamines and antidepressants.
  • Precursor for p-tolualdehyde oximes, used in pesticide production.
• Chemical Synthesis:
  • Building block for dyes, resins, and polymers (e.g., polyimides).
  • Intermediate in the preparation of p-toluic acid and p-methylbenzoic acid derivatives.
• Organic Chemistry Research:
  • Used in academic studies for aldol condensations, Wittig reactions, and other carbon-carbon bond-forming reactions.

Safety and Handling

• Hazards:
  • Toxicity: Harmful if ingested or inhaled; causes skin and eye irritation.
  • Flammability: Combustible liquid; vapor may form explosive mixtures with air.
  • Oxidative Risk: Slowly oxidizes to p-toluic acid, which may affect product purity.
• Storage and Precautions:
  • Store in a cool, dark, well-ventilated area, sealed in airtight containers to prevent oxidation.
  • Use gloves and goggles when handling; avoid contact with skin, eyes, and clothing.
  • Extinguish fires with dry chemical, CO2, or foam extinguishers.
