Sodium formate, HCOONa, is the sodium salt of formic acid, HCOOH. It usually appears as a white deliquescent powder. Sodium formate crystallizes in a monoclinic crystal system with the lattice parameters a = 6,19 Å, b = 6,72 Å, c = 6,49 Å und β = 121. 

Sodium formate is used in several fabric dyeing and printing processes. It is also used as a buffering agent for strong mineral acids to increase their pH, as a food additive (E237), and as a de-icing agent.

In structural biology, sodium formate can be used as a cryoprotectant for X-ray diffraction experiments on protein crystals,[6] which are typically conducted at a temperature of 100 °K to reduce the effects of radiation damage.
