Application
Heptanoic acid, also known as enanthic acid, is a seven carbon straight chain saturated fatty acid that serves as a versatile organic building block. In the pharmaceutical industry, it is essential for the esterification of steroids and the preparation of active pharmaceutical ingredients including trenbolone enanthate, testosterone enanthate, drostanolone enanthate, and methenolone enanthate. In the flavor and fragrance sector, heptanoic acid is used to produce esters for flavoring and fragrance formulations, and is found naturally in the flavor volatiles of cheese, green tea, and certain fruits. Its ester derivatives are widely used in cosmetics and industrial lubricants for aviation, refrigeration, and automotive applications. Heptanoic acid also serves as a comonomer in alkyd resin production, as a precursor for synthesizing sodium heptanoate (a corrosion inhibitor), and as an internal standard during gas chromatography analysis of volatile acids. Additionally, it is used to synthesize triheptanoin via esterification with glycerol, to produce 1 hexene through decarbonylation, and to synthesize 7 tridecanone by ketonization. Heptanoic acid is listed on the positive list of EU regulation 10/2011 for plastics intended to come into contact with food.

FAQ
Q1 How should heptanoic acid be stored safely?
A Store in a cool, dry, well ventilated area away from strong oxidizing agents, bases, and active metals. Keep container tightly sealed. Shelf life is 24 months under recommended conditions.
Q2 What purity grades do you supply?
A Standard grade is 99.0 percent by GC. We also supply 98 percent and 99.5 percent grades for different applications.
Q3 Is heptanoic acid soluble in water?
A Slightly soluble in water (about 2.82 g per L at 25 degrees Celsius). Freely miscible with ethanol, acetone, diethyl ether, and most organic solvents.
Q4 Do you provide sample quantities for formulation development?
A Yes, free samples of 100 mL are available for qualified US companies. Shipping fee applies for small quantities.
Q5 What are the common impurities in heptanoic acid and how do you control them?
A Key impurities include water and other fatty acids. Our specification limits water below 0.1 percent. Full impurity profile provided per batch.
Q6 What safety measures are required when handling heptanoic acid?
A Heptanoic acid is corrosive and can cause severe injury to skin, eyes, and respiratory tract. Use in a fume hood with full PPE including chemical resistant gloves, goggles, and lab coat. In case of contact, rinse immediately with plenty of water and seek medical attention.
