Sodium Hexanoate (CAS 19766-89-3), also known as sodium caproate, is the sodium salt of hexanoic acid that appears as a white to off-white crystalline powder and is used in the synthesis of biodegradable biopolymers, as a food flavoring agent, and as an intermediate for esters. It is soluble in water and ethanol, with a faint fatty odor, pH alkaline in solution, and derived from hexanoic acid neutralization. Stable under normal conditions but hygroscopic.

Sodium Hexanoate
Applications
Used in synthesis of biodegradable biopolymers, food as a flavoring agent, pharmaceuticals for drug delivery, and in cosmetics as an emulsifier; also in animal feed additives and chemical intermediates for esters.
Safety & Risks
Irritant to skin and eyes; may cause respiratory issues if inhaled. Combustible; avoid strong oxidizers to prevent reactions. Low toxicity but handled with PPE; stable but decomposes on heating emitting acrid smoke.
Packaging
In 25kg drums or bags with PE liners; store in cool, dry places; rinse triply for recycling or puncture for landfill disposal.
