Methyl 2-hydroxybenzoate

Methyl 2-hydroxybenzoate is an organic chemical compound with the molecular formula C8H8O3 and CAS number 119-36-8. Also known as methyl salicylate or oil of wintergreen, it belongs to the ester family and has a molecular weight of 152.15 g/mol. This compound is classified as a reproductive toxicant category 2, acute toxin category 4, and skin sensitizer category 1B under CLP regulation, requiring careful handling in industrial applications.

Methyl 2-hydroxybenzoate is typically a colorless to pale yellow liquid at room temperature with a characteristic sweet, minty odor reminiscent of wintergreen. It has good solubility in alcohol and oils but limited solubility in water. The compound has a boiling point around 222°C and a density of approximately 1.17 g/cm³. Its ester structure makes it relatively stable under normal conditions but sensitive to hydrolysis in alkaline environments.

Methyl 2-hydroxybenzoate is primarily used in the fragrance and flavor industry as a wintergreen flavoring agent in food products, cosmetics, and pharmaceuticals. It serves as an intermediate in organic synthesis for producing other salicylate derivatives. The compound is also utilized in topical analgesic preparations due to its anti-inflammatory properties and finds applications in the manufacture of UV filters and preservatives for various industrial formulations.

Methyl 2-hydroxybenzoate requires careful handling due to its reproductive toxicity and skin sensitization potential. Always wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Ensure adequate ventilation in work areas and avoid direct skin contact or inhalation of vapors. Use the substance only in controlled industrial environments with proper training, as it poses acute toxicity risks and may cause allergic skin reactions upon exposure.

Methyl 2-hydroxybenzoate should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep containers upright and protected from physical damage. Store separately from strong oxidizers, acids, and bases to prevent incompatible reactions. Maintain storage temperatures below 25°C when possible and ensure proper labeling with hazard information. Implement appropriate spill containment measures and restrict access to authorized personnel only.

Methyl 2-hydroxybenzoate exposure requires immediate action due to its toxicity profile. For skin contact, immediately remove contaminated clothing and wash affected area thoroughly with soap and water for at least 15 minutes. If eye contact occurs, rinse with clean water for 15 minutes and seek medical attention. In case of inhalation, move to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical care. Always consult a physician after any significant exposure.

Methyl 2-hydroxybenzoate disposal must comply with local and European waste regulations due to its hazardous classification. The substance should be treated as hazardous chemical waste and disposed of through licensed waste management facilities. Never discharge into sewers, waterways, or soil as it may cause environmental harm (Aquatic Chronic 3). Small quantities may be incinerated at appropriate high-temperature facilities. Always consult local authorities and waste disposal experts for specific disposal requirements in your region.

Methyl 2-hydroxybenzoate transport should follow general chemical shipping guidelines as no specific ADR classification is assigned to this substance. Use appropriate packaging that prevents leakage and damage during transit. Ensure proper labeling with hazard pictograms (GHS07, GHS08) and safety information. Transport vehicles should be equipped with emergency response equipment and drivers properly trained in chemical handling. Follow national and international regulations for chemical transport and maintain proper documentation throughout the shipping process.

Methyl 2-hydroxybenzoate is subject to REACH regulation requiring registration for commercial use in the European Union. Under CLP regulation, it must be classified and labeled with Warning signal word and appropriate GHS pictograms (GHS07, GHS08). The substance is not currently listed as a Substance of Very High Concern (SVHC). Users must comply with occupational exposure limits, reproductive toxicity restrictions, and environmental protection measures. Always check current regulatory status as requirements may change.
