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. [5]
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 .

A. R. Forouhi and I. Bloomer deduced dispersion equations for the refractive index, n, and extinction coefficient, k, which were published in 1986 [1] and 1988. [2] The 1986 publication relates to amorphous materials, while the 1988 publication relates to crystalline.

Extinction coefficient refers to several different measures of the absorption of light in a medium: Attenuation coefficient , sometimes called "extinction coefficient" in meteorology or climatology Mass extinction coefficient , how strongly a substance absorbs light at a given wavelength, per mass density

One could write speciifcally about the test-reagent as a chemical, and specifically about the test protocol, but the two are inter-related and at least at this time doesn't seem like sufficient material to make either of those substantially long pages.
