Ellman's original 1959 publication estimated the molar extinction at 13,600 M −1 cm −1, and this value can be found in some modern applications of the method despite improved determinations. [6] Commercial DTNB may not be completely pure, so may require recrystallization to obtain completely accurate and reproducible results.
tert-Butanesulfinamide (also known as 2-methyl-2-propanesulfinamide or Ellman's sulfinamide) is an organosulfur compound and a member of the class of sulfinamides. Both enantiomeric forms are commercially available and are used in asymmetric synthesis as chiral auxiliaries , often as chiral ammonia equivalents for the synthesis of amines .
Sounds like neutral NTB, even if it is technically formed, immediately would ionize (twice), so maybe a second scheme with that process would be simplest solution? Need to have the description match the equation. And especially important to have the structure of the NTB 2-form, since that's the key to the reagent's notability. The intermediate ...
In metallurgy, Keller's reagent is a mixture of nitric acid, hydrochloric acid, and hydrofluoric acid, used to etch aluminum alloys to reveal their grain boundaries and orientations. [1] It is also sometimes called Dix–Keller reagent , after E. H. Dix, Jr., and Fred Keller of the Aluminum Corporation of America , who pioneered the use of this ...
Due to steric hindrance of the adjacent neopentyl-like moiety, PETN is resistant to attack by many chemical reagents; it does not hydrolyze in water at room temperature or in weaker alkaline aqueous solutions. Water at 100 °C or above causes hydrolysis to dinitrate; presence of 0.1% nitric acid accelerates the reaction.
Dithiothreitol (DTT) is an organosulfur compound with the formula (CH(OH)CH 2 SH) 2.A colorless compound, it is classified as a dithiol and a diol.DTT is redox reagent also known as Cleland's reagent, after W. Wallace Cleland. [2]

Fenton's reagent is a solution of hydrogen peroxide (H 2 O 2) and an iron catalyst (typically iron(II) sulfate, FeSO 4). [1] It is used to oxidize contaminants or waste water as part of an advanced oxidation process. Fenton's reagent can be used to destroy organic compounds such as trichloroethylene and tetrachloroethylene (perchloroethylene
