Category	Details
Chemical Properties	Bispyribac sodium is a white odorless powder with a molecular formula of C19H17N4NaO8 and a molecular weight of 452.35.
Physical Properties	Melting point: 223–224°C. Boiling point: 686.4°C at 760 mmHg. Density: 1.47 g/cm³.
Solubility	Soluble in water (73.3 g/L at 20°C). Solubility in methanol: 25 g/L at 20°C; in ethyl acetate: 61 mg/L; in n-hexane: 8.34 mg/L; in acetone: 1.4 g/L; in toluene: <1 mg/L; in dichloromethane: 1.2 g/L (all at 25°C).
Environmental Fate	In soil, Bispyribac sodium is expected to be immobile due to its high Koc value (1.7×10⁴), but it exists mainly as an anion in the environment, reducing its adsorption to soil. It is not expected to volatilize from moist or dry soil surfaces.
Toxicity	LD50 in male rats: 4111 mg/kg; in female rats: 2635 mg/kg (oral). LC50 in bluegill sunfish and rainbow trout: >100 ppm.
Storage Conditions	Store in a cool, dry place, protected from moisture.
