Results and discussion

Effect levels
Sex:
male
Dose descriptor:
LD50
Effect level:
2.72 other: g/kg bw
Based on:
test mat.
95% CL:
2.07 - 3.56
Other findings:
Based on the experimental results obtained with the analogue Potassium Acetate (LD 50 for male rats = 3.25 (2.48-4.26) g/kg) and the molecular weights, the read-across approach is applied and the LD50 for substance Sodium Acetate is calculated to be 2.72 (2.07-3.56) g/kg.

The analogue Potassium Acetate which shares the same functional group with Sodium Acetate, also has comparable values for the relevant molecular properties. These properties are:
- a low log Pow value which is -3.72 for Potassium Acetate and for Sodium Acetate,
- a similar water solubility which is 2.5 g/mL at 20 ºC for Potassium Acetate and 1.25 g/mL for Sodium Acetate at 25 ºC, and
- similar molecular weights which are 98.14 for Potassium Acetate and 82.03 for Sodium Acetate.
