The <br />half-life of chloropicrin in air exposed to simulated sunlight was 20 days (292). The photoproducts <br />were phosgene (which will hydrolyze to carbon dioxide and hydrogen chloride), nitric oxide, <br />chlorine, nitrogen dioxide and dinitrogen tetroxide. <br />Analytical Methods: The concentration of chloropicrin in air may be measured using Kitagawa <br />direct reading gas detector tube#172 (Matheson -Kitagawa, East Rutherford, NJ). Gas <br />chromatography methods are available to measure chloropicrin in air (283) and may utilize XAD-4 <br />solid sorbent tubes (SKC Inc., Eighty Four, PA). <br />PHYSICAL PROPERTIES AND GUIDELINES <br />Physical Properties: <br />• Appearance: Heavy, colorless, liquid with a sharp odor <br />• Chemical Names: Trichloronitromethane; Methane, trichIoronitro; Nitrotrichloro-methane, <br />Nitrochloroform <br />• CAS Number: 76-06-2 <br />• Molecular Weight: 164.38 <br />• Water Solubility: 1.6 g/L @ 25 degrees C <br />• Solubility in Other Solvents: Miscible in most organic solvents <br />• Melting Point: -64 degrees C <br />• Vapor Pressure: 18.3 mmHg @ 20 degrees C, 24 mmHg @ 25 degrees C <br />• Partition Coefficient: Not Available <br />• Adsorption Coefficient: Not Available <br />Exposure Guidelines: <br />• ADI: Not Available <br />• MCL: Not Available <br />• RfD: Not Available <br />• PEL: 0.1 ppm <br />• HA: Not Available <br />• TLV: 0.1 ppm TWA <br />BASIC MANUFACTURERS <br />Niklor Chemical Corp. <br />2060 E. 220th Street <br />Long Beach, CA 90810 <br />REFERENCES: <br />References for the information in this PIP can be found in Reference List Number 10 <br />DISCLAIMEIZ: The information in this profile does not in any way replace or supersede the information <br />on the pesticide product label/ing or other regulatory requirements.
