Potassium gluconate is the potassium salt of the conjugate base of gluconic acid. It is also referred to as 2,3,4,5,6-pentahydroxycaproic acid potassium salt, D-gluconic acid potassium salt, or potassium D-gluconate.[1]

It contains 16.69% potassium by mass. Thus 5.99 g of potassium gluconate contains 1 g of potassium.

It has a density of 1.73 g/cm3.[2]
