PRODUCT INTRODUCTION
description
Diphosgene is a moderately persistent synthetic organic compound, formed by chlorination of methyl chloroformate, that is a respiratory irritant and lachrymator. Trichloromethyl Chloroformate has been used as a chemical warfare agent and is characterized as a colorless liquid with an odor that is like newly mown hay. Exposure occurs by inhalation, ingestion, or contact.
