Sinalbin is a glucosinolate found in the seeds of white mustard, Sinapis alba. In contrast to mustard from black mustard (Brassica nigra) seeds, containing sinigrin), mustard from white mustard seeds has only a weakly pungent taste. [fr RICHARD H. Arômes alimentaires [http://www.cnrs.fr/chimie/communication/images/images-chimietous/minidossiers/cours%20aromes_hubert%20richard.pdf Document de cours] ]

The less sharp taste is due to the fact that the mustard oil from this specific glucosinolate, 4-hydroxybenzyl isothiocyanate, is unstable. With a half life of one or a few hours, the pungent mustard oil degrades to 4-hydroxybenzyl alcohol and thiocyanate ion, which are not pungent. Glucobrassicin is a structurally related glucosinolate that likewise yields a non-pungent isothiocyanate due to reaction with water.

Chemical name of sinalbin is p-Hydroxybenzylglucosinolate and cas number: 19253-84-0.
