CAS 503-38-8

Diphosgene

Description:

Diphosgene, with the CAS number 503-38-8, is a chemical compound that serves primarily as an intermediate in organic synthesis and as a reagent in the production of various pharmaceuticals and agrochemicals. It is a colorless to pale yellow liquid with a sweet odor, reminiscent of that of chloroform. Diphosgene is classified as a toxic substance, and it is known to be a potent respiratory irritant, posing significant health risks upon inhalation or skin contact. Its chemical structure consists of two carbonyl groups linked by a carbon atom, making it a derivative of phosgene. Due to its toxicity, diphosgene must be handled with extreme caution in well-ventilated areas, using appropriate personal protective equipment. In terms of stability, it is relatively stable under normal conditions but can decompose when exposed to moisture or high temperatures. Overall, diphosgene is an important compound in synthetic chemistry, but its hazardous nature necessitates strict safety protocols during its use and handling.

Diphosgene

CAS: 503-38-8

Diphosgene is an organic compound that is a colorless gas at standard temperature and pressure. It is a chlorinating agent, meaning that it can react with hydrogen to form chlorine gas. Diphosgene has been used as an alveolar type of lung irritant, which induces emphysema by reacting with the hydroxyl group on the surface of lung cells. It also causes apoptosis in liver cells through the gamma-aminobutyric acid pathway. Diphosgene's most common use is as a phosgene precursor in the production of pentobarbital sodium.
