The Potassium lactate, with the CAS registry number 996-31-6 and EINECS registry number 288-752-8, has the systematic name and IUPAC name of potassium 2-hydroxypropanoate. It is also known as propanoic acid, 2-hydroxy-, potassium salt (1:1). And the molecular formula of this chemical is C₃H₅KO₃.

It is the potassium salt of lactic acid, and can be produced by neutralizing lactic acid which is fermented from a sugar source. As it has a broad antimicrobial action and is effective at inhibiting most spoilage and pathogenic bacteria, it is usually used in meat and poultry products to extend shelf life and increase food safety. It is also used as an extinguishing media in the First Alert Tundra fire extinguishers.

The physical properties of Potassium lactate are as following: (1)ACD/LogP: -0.70; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): -2.76; (4)ACD/LogD (pH 7.4): -4.24; (5)ACD/BCF (pH 5.5): 1; (6)ACD/BCF (pH 7.4): 1; (7)ACD/KOC (pH 5.5): 1; (8)ACD/KOC (pH 7.4): 1; (9)#H bond acceptors: 3; (10)#H bond donors: 2; (11)#Freely Rotating Bonds: 2; (12)Polar Surface Area: 46.53 Å²; (13)Flash Point: 109.9 °C; (14)Enthalpy of Vaporization: 53.96 kJ/mol; (15)Boiling Point: 227.6 °C at 760 mmHg; (16)Vapour Pressure: 0.015 mmHg at 25°C.
