Niacet Anhydrous Hydrogen Chloride
Anhydrous Hydrogen Chloride (HCl) is a colorless, corrosive, toxic, nonflammable gas with a suffocating odor. Hydrogen Chloride is heavier than air and fumes strongly in moist environments. It is shipped as a liquefied gas under its own vapor pressure. Our process imparts few impurities that may impact your process, you benefit from our clean manufacturing systems.
