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 is an ester derived from salicylic acid and methanol. With a molecular weight of 152.15 g/mol, this compound appears as a colorless to pale yellow liquid with a characteristic sweet, minty odor reminiscent of wintergreen.

Methyl 2-hydroxybenzoate is a colorless to pale yellow liquid at room temperature with a distinctive sweet, wintergreen-like odor. It has a molecular weight of 152.15 g/mol and is slightly soluble in water but readily soluble in alcohol, ether, and other organic solvents. The compound has a boiling point around 223°C and a density of approximately 1.17 g/cm³ at 20°C.

Methyl 2-hydroxybenzoate is primarily used as a flavoring agent in food products, cosmetics, and pharmaceutical preparations due to its wintergreen scent. It serves as an intermediate in organic synthesis and is employed in the production of perfumes, liniments, and topical analgesic formulations. Additionally, it finds applications as a UV filter in some cosmetic products and as a fragrance component in various consumer goods.

Methyl 2-hydroxybenzoate requires careful handling due to its classification as Acute Tox. 4, Repr. 2, and Skin Sens. 1B. Use appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Ensure adequate ventilation in work areas and avoid skin contact and inhalation. Handle in well-ventilated areas away from heat sources, and wash hands thoroughly after use to prevent sensitization reactions.

Methyl 2-hydroxybenzoate should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Keep containers upright and properly labeled according to CLP regulations with appropriate warning pictogrammes (GHS07, GHS08). Store away from incompatible materials such as strong oxidizing agents and bases. Maintain storage temperature below 25°C to prevent degradation and ensure container integrity.

In case of skin contact with methyl 2-hydroxybenzoate, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. If eye contact occurs, rinse immediately with plenty of clean water for 15 minutes and seek medical attention. In case of inhalation, move to fresh air immediately. If ingested, do not induce vomiting and seek immediate medical attention due to its acute toxicity classification.

Methyl 2-hydroxybenzoate must be disposed of as hazardous waste according to local and European waste regulations. Do not discharge into drains, waterways, or soil due to its Aquatic Chronic 3 classification. Contact authorized waste disposal companies for proper treatment and disposal. Small quantities may be incinerated at approved high-temperature facilities. Always consult local environmental authorities for specific disposal requirements and waste codes.

Methyl 2-hydroxybenzoate can be transported without specific ADR dangerous goods classification for road transport within Europe. However, packages must be properly labeled with appropriate GHS pictogrammes (GHS07, GHS08) and safety information according to CLP regulation. Use appropriate packaging materials resistant to the chemical and ensure containers are tightly sealed to prevent leakage during transport. Follow general chemical transport safety guidelines.

Methyl 2-hydroxybenzoate is subject to REACH regulation and must be registered for import/manufacture above one tonne annually. It is classified under CLP regulation with hazard classes Repr. 2, Acute Tox. 4, Skin Sens. 1B, and Aquatic Chronic 3, requiring appropriate labeling with warning signal word. While not currently listed as SVHC, its reproductive toxicity classification may require special attention in workplace risk assessments and safety data sheets.
