Nonanoic acid

Nonanoic acid is a saturated carboxylic acid with nine carbon atoms and the molecular formula C9H18O2. Also known as pelargonic acid, it is a naturally occurring fatty acid found in various plant oils and animal fats. With a molecular weight of 158.24 g/mol, nonanoic acid appears as a colorless to pale yellow liquid with a characteristic rancid odor at room temperature.

Nonanoic acid is a colorless to pale yellow liquid at room temperature with a distinctive rancid, fatty odor. It has a molecular weight of 158.24 g/mol and is slightly soluble in water but readily soluble in organic solvents like ethanol and ether. The compound has a melting point around 12°C and a boiling point of approximately 254°C, making it stable under normal storage conditions.

Nonanoic acid is primarily used as a herbicide and plant growth regulator in agriculture, effectively controlling weeds and moss. It serves as an intermediate in the production of esters, plasticizers, and lubricants in the chemical industry. Additional applications include its use in cosmetics and personal care products, as well as in the manufacture of specialty chemicals and pharmaceutical intermediates.

Nonanoic acid should be handled with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing to prevent skin and eye contact. Work in well-ventilated areas or use local exhaust ventilation to minimize inhalation exposure. The substance is classified as Skin Irritant Category 2 and Eye Irritant Category 2, requiring careful handling to avoid direct contact with skin and eyes.

Nonanoic acid should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Keep containers upright and properly labeled according to GHS requirements with Warning signal word and GHS07 pictogram. Store away from strong bases, oxidizing agents, and metals to prevent unwanted reactions. Ensure storage areas comply with local fire safety regulations.

Skin contact with nonanoic acid requires immediate removal of contaminated clothing and thorough washing of affected areas with soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for at least 15 minutes while holding eyelids open. If irritation persists or if the substance is ingested, seek immediate medical attention and provide the safety data sheet to healthcare professionals.

Nonanoic acid must be disposed of according to local and national waste regulations as hazardous chemical waste. Do not discharge into drains, waterways, or soil as it is classified as Aquatic Chronic Category 3. Contact licensed waste disposal companies for proper collection and treatment. Small quantities may be neutralized with appropriate bases under controlled conditions before disposal, following local environmental guidelines.

Nonanoic acid is classified as ADR Class 8 (Corrosive substances), Packing Group III for transportation purposes. It must be packaged in UN-approved containers with proper labeling including the corrosive hazard diamond. Transport documents must include the correct shipping name, UN number, and emergency response information. Vehicles must comply with ADR regulations for Class 8 substances during transport.

Nonanoic acid is regulated under the EU CLP Regulation with classification as Skin Irritant 2, Eye Irritant 2, and Aquatic Chronic 3, requiring appropriate labeling with Warning signal word and GHS07 pictogram. It falls under REACH registration requirements for manufacturers and importers. The substance is not classified as SVHC (Substance of Very High Concern) and has no specific use restrictions under current EU legislation.
