Application
2-Pentadecanone is mainly used as food additives, chemical reagents, fine chemicals, pharmaceutical intermediates and material intermediates. It is used as an intermediate in the pharmaceutical field to synthesize a variety of drugs, and can also be used to synthesize products such as spices and flavors.
The application of 2-pentadecanone in the food field is mainly reflected in its use as a food additive, especially as a food flavor. 2-pentadecanone is classified as a GRAS (generally recognized as safe) substance, and the use limit set by FEMA is 75.0mg/kg. In addition, according to GB 2760 standard, the use of 2-pentadecanone as a food flavor should ensure that each flavor component does not exceed the maximum allowable usage amount and the maximum allowable residue.
In addition, 2-pentadecanone may be used to prepare flavors to increase the aroma and flavor of food, which is particularly common in processed foods that require specific aromas.
When storing 2-pentadecanone, the container should be kept sealed and stored in a cool, dry place to avoid contact with oxides. In terms of first aid measures, if inhaled, the patient should be moved to fresh air, and the skin should be thoroughly rinsed with soapy water and clean water after contact, and the eyes should be rinsed with running clean water or saline after contact, and medical treatment should be sought immediately after ingestion.
In terms of firefighting measures, it is recommended to use water mist, dry powder, foam or carbon dioxide fire extinguishing agents, and avoid using direct water to extinguish fires to prevent the spread of fire. During operation and disposal, avoid contact with eyes and skin, stay away from fire and heat sources, and use explosion-proof ventilation systems and equipment.
