ammonia cas number
Ammonia or azane is a compound of nitrogen and hydrogen with the formula NH3. The simplest pnictogen hydride, ammonia is a colourless gas with a characteristic pungent smell. It contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers. Household ammonia or ammonium hydroxide is a solution of NH3 in water. The concentration of such solutions is measured in units of the Baumé scale (density), with 26 degrees baumé (about 30% (by weight) ammonia at 15.5 °C or 59.9 °F) being the typical high-concentration commercial product. (APF = 50) Any chemical cartridge respirator with a full facepiece and cartridge(s) providing protection against the compound of concern. (APF = 50) Any air-purifying, full-facepiece respirator (gas mask) with a chin-style, front- or back-mounted canister providing protection against the compound of concern. (APF = 50) Any self-contained breathing apparatus with a full facepiece. (APF = 50) Any supplied-air respirator with a full facepiece. Ammonia as Nitrogen.

CAS Number: 7664-41-7. EC Number (EINECS): 231-635-3. Synonyms: Ammonia gas;Nitro-Sil;Spirit of Hartshorn;NH3;Ammonia, anhydrous;Anhydrous ammonia;Aromatic Ammonia, Vaporole. Appearance: colourless gas with a penetrating, suffocating odour. Ammonia (gas) - CAS # 7664-41-7. Information provided on Ammonia (gas) (7664-41-7) is for reference only and is subject to change. There is no warranty of accuracy or completeness of any information contained herein. Ammonia is a colourless gas with a characteristic pungent smell. It is lighter than air, its density being 0.589 times that of air. It is easily liquefied due to the strong hydrogen bonding between molecules; the liquid boils at −33.3 °C (−27.94 °F), and freezes at −77.7 °C (−107.86 °F) to white crystals. • For 294993-170G: Stainless steel control valves Z146951, Z187224 or either of stainless steel regulators Z148504 and Z148512 and a T-purge valve Z151661 is recommended. • For 294993-230G-EU: outlet fitting: DIN 477-1 no. 1, Z742162 or Z742164 are the recommended regulators.
