America's whole supply of chlorpicrin during the war came from the American Synthetic Color Co. and the Edgewood Arsenal. The Stamford plant was the first to reach large-scale production.
The contract with the American Synthetic Color Co. was dated December 13, 1917; and the company shipped over 111,853 pounds of the gas to Edgewood on March 11. This, when mixed with the necessary stannic chloride, supplies of which were already on the ground, was sufficient to fill approximately 100,000 75-millimeter shell. In the spring of 1918, due to certain internal troubles at the Stamford plant, it was agreed that the United States should lease this factory and operate it as a Government plant. Under Government operation the total production of chlorpicrin at the Stamford plant amounted to 3,226,000 pounds, of which 2,703,300 pounds were shipped overseas in 660-pound drums.
