Repeated exposures to 1/10 of the LCt 50 did not produce overt systemic toxicity or significant pathology. [7] MSF can also cause severe skin burns and serious eye damage, if contact is made. It is a lachrymator and its vapor causes tears in eyes. [8] [2] Methanesulfonyl fluoride has a pungent odor.
PMSF does not inactivate all serine proteases. [1] The effective concentration of PMSF is between 0.1 - 1 mM. The half-life is short in aqueous solutions (110 min at pH 7, 55 min at pH 7.5, and 35 min at pH 8, all at 25 °C). [2] At 4˚C, pH 8, PMSF is almost completely degraded after 1 day. [2]
Sulfuryl fluoride (also spelled sulphuryl fluoride) is an inorganic compound with the formula SO 2 F 2. It is an easily condensed gas and has properties more similar to sulfur hexafluoride than sulfuryl chloride , being resistant to hydrolysis even up to 150 °C. [ 3 ]
2.5 mg/kg (oral, mice) [2] Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Infobox references
The LD 50 of MSM is greater than 17.5 grams per kilogram of body weight. [16] Extensive research in animal models indicates MSM has a very low toxicity when administered both orally and topically. [17] [18] [19] MSM is considered 'Possibly Safe' at therapeutic doses. [13] [20]
U.S. standards recommend fluoride levels of 0.7 milligrams per liter of water, and the NTP’s conclusion applied to water fluorinated at 1.5 milligrams per liter and above.
Methanesulfonyl chloride (mesyl chloride) is an organosulfur compound with the formula CH 3 SO 2 Cl. Using the organic pseudoelement symbol Ms for the methanesulfonyl (or mesyl) group CH 3 SO 2 –, it is frequently abbreviated MsCl in reaction schemes or equations. It is a colourless liquid that dissolves in polar organic solvents but is ...
A-242 has been added to Schedule 1 of the Annex on Chemicals of the Chemical Weapons Convention as of June 2020, and it has been explicitly named as an example compound for schedule 1.A.15. [ 2 ] [ 3 ] For chemicals listed in Schedule 1, the most stringent declaration and verification measures are in place combined with far-reaching limits and ...
