EC number: 809-920-4 | CAS number: 1047637-37-5
Highest achievable test chamber concentration: nominal: 4.5 mg/L, measured in animal breathing zone: 1.65 mg/L
Percentage of particles < 3.5 micro m: 70.2 weight percent, mass median aerodynamic diameter: 2.5 micro m.
In an acute inhalation toxicity study conducted according to OECD Guideline No.403, male and female Sprague-Dawley rats were exposed by inhalation route to 2,2-bis(chloromethyl)trimethylene bis(bis(2-chloroethyl)phosphate) for 4 hours nose only at concentrations of 1.65 mg/L (limit test). This was the highest attainable concentration, due to the viscous nature of the test material.
Animals were observed for up to 14 days. No mortalities were observed during the course of the study.
LC50 males > 1.65 mg/L
LC50 females > 1.65 mg/L
