Formula: C7H4Cl3NO3
Molecular mass: 256.5
Decomposes at 208°C
Melting point: 148-150°C
Density: 1.85 g/cm³
Solubility in water, g/100ml at 25°C: 0.04 (none)
Vapour pressure at 25°C: negligible
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.00 


EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion. 

Effects of short-term exposure
May cause mechanical irritation. 

Inhalation risk
A nuisance-causing concentration of airborne particles can be reached quickly when dispersed. 

Effects of long-term or repeated exposure
 


OCCUPATIONAL EXPOSURE LIMITS
 

ENVIRONMENT
This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal.
