Molar mass: 546.79 Melting point: 95 to 98 °C (203 to 208 °F; 368 to 371 K) Except where otherwise noted, data are given for materials in their standard state ...
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.

Molar concentration or molarity is most commonly expressed in units of moles of solute per litre of solution. [2] For use in broader applications, it is defined as amount of substance of solute per unit volume of solution, or per unit volume available to the species, represented by lowercase c {\displaystyle c} : [ 3 ]
Tetramethylammonium hydroxide (TMAH or TMAOH) is a quaternary ammonium salt with molecular formula N(CH 3) 4 + OH −.It is commonly encountered in form of concentrated solutions in water or methanol.
