HEPTANOIC ACID Chemical compatibility with O-rings, rubbers, & plastics

Heptanoic acid, also known as enanthic acid, is a seven-carbon saturated fatty acid with the molecular formula C7H14O2. It is a colorless, oily liquid with an unpleasant, rancid odor. Heptanoic acid is used in the production of esters for fragrances and flavors, as well as in the synthesis of pharmaceuticals and lubricants. It serves as an intermediate in organic synthesis and can be used as a preservative in some formulations. Heptanoic acid is slightly soluble in water but highly soluble in organic solvents. Handling heptanoic acid requires caution as it can cause skin and eye irritation upon contact. Proper storage involves keeping it in a cool, well-ventilated area away from incompatible substances. Heptanoic acid's applications in various industries highlight its importance as a versatile chemical compound.
