Product Parameters
Basic Properties
1. Physical Properties
Appearance: White to off-white crystalline powder with no noticeable odor. Higher product purity results in more uniform crystal color.
Melting point range is stable, with pure product typically melting between 77-79°C. Beyond this temperature, gradual melting occurs accompanied by slight decomposition.
Density is approximately 1.16 g/cm³. It remains stable under standard temperature and pressure, is non-volatile, and exhibits low hygroscopicity.
2. Chemical Properties
Molecular formula: C₉H₁₀O₂; molecular weight: 150.18. The molecular structure contains a carboxyl group (-COOH), imparting typical organic acid chemical characteristics.
It undergoes neutralization reactions with alkalis to form corresponding o-methylbenzoic acid salts, such as sodium o-methylbenzoate when reacting with sodium hydroxide.
It participates in esterification reactions, forming o-methylbenzoic acid esters with alcohols (e.g., methanol, ethanol) under catalysis. This reaction principle forms the core of its application in fragrance synthesis.
3. Solubility
Solubility exhibits distinct selectivity. It readily dissolves in organic solvents like ethanol, diethyl ether, and chloroform, forming clear, transparent solutions.
It is slightly soluble in water, with a solubility of approximately 0.3 g/100 mL at 20°C. Solubility increases slightly with rising water temperature, though the increase is limited.
Main Applications
In the pharmaceutical sector, it serves as a key raw material for synthesizing antihistamines (such as loratadine intermediates) and antihypertensive drugs (angiotensin inhibitor precursors). It is also used in preparing nonsteroidal anti-inflammatory drugs. As it directly impacts drug efficacy and safety, a purity of ≥99.5% is required. Our product precisely meets pharmaceutical-grade standards.
In the fragrance sector, it synthesizes floral and fruity aroma components for high-end cosmetic products, requiring low odor and high stability. Through process optimization, we effectively control odor issues caused by impurities.
In the dye industry, it serves as an intermediate for synthesizing azo dyes and acid dyes, enhancing dyeing efficiency and colorfastness. Industrial-grade products meet mass production demands, and our annual production capacity of 500 tons ensures stable supply.
Safety Precautions
1. Safety Precautions
Wear dust masks and nitrile gloves during operation to prevent powder inhalation or direct skin contact, avoiding mild irritation. If skin contact occurs, immediately rinse with soap and water.
Strictly prohibit large-scale operations in non-ventilated areas to prevent accumulation of volatile organic solvent gases. Keep separate from oxidizers and strong acids to avoid chemical reactions.
Pharmaceutical-grade products must be processed using dedicated equipment to prevent cross-contamination with industrial-grade raw materials, ensuring safety in subsequent drug synthesis.
2. Storage Safety
Store in a cool, dry, well-ventilated warehouse at temperatures below 25°C. Keep away from fire and heat sources to prevent property changes due to high temperatures.
Use sealed polyethylene packaging. Store in separate zones from strong oxidizing agents, strong alkalis, and other chemicals. Clearly label packaging with “Organic Intermediate” and purity grade to prevent misuse.
3. Emergency Response
If powder is inhaled, immediately move to fresh air. Seek medical attention promptly if coughing or chest tightness occurs. If powder enters eyes, flush with copious amounts of running water for 15 minutes before seeking medical care.
In case of spillage, cover and collect with dry sand to prevent dust dispersion. Do not dispose of carelessly. Handle according to hazardous chemical waste disposal regulations.
