What is the difference between thiocyanate and isothiocyanate?
The key difference between thiocyanate and isothiocyanate is that a thiocyanate is a functional group in which the alkyl or aryl group gets attached through the sulfur atom, whereas isothiocyanate is the linkage isomer of thiocyanate in which the alkyl or aryl group gets attached through the nitrogen atom.
Why is iron thiocyanate important?
Thiocyanate is one of the most important spectrophotometric reagents. The availability of the reagent and the simplicity of thiocyanate methods are responsible for its great popularity in analytical laboratories [131,132]. Thiocyanate is principally used for determination of Fe(III), Mo, W, Nb, Re, Co, U, and Ti.

What is isothiocyanate used for?
Isothiocyanates are naturally occurring small molecules that are formed from glucosinolate precursors of cruciferous vegetables. Many isothiocyanates, both natural and synthetic, display anticarcinogenic activity because they reduce activation of carcinogens and increase their detoxification.
Is allyl isothiocyanate volatile?
Allyl isothiocyanate (AIT) is a volatile and aliphatic sulfur-containing compound naturally occurring in plants from the family of the Cruciferae.
Is thiocyanate a reducing agent?
Thiocyanate ions are found to be an effective reducing agent for the decolorization of methylene blue under ambient condition. The salting-in agent urea has been found to uniquely enhance the rate of the reduction of MB by thiocyanate ion in the presence of micelles.
Why is NCS a stronger ligand than SCN?
The sulphur atom is larger in size with vacant 3d orbitals. Though nitrogen is more electronegative, it is smaller in size without any extra vacant orbitals. This makes the nitrogen atom a better electron donor than sulphur to bond with transition metal ions. So, NCS- acts as the stronger ligand between the two.
Is the formation of iron thiocyanate exothermic or endothermic?
The red color of Solution 7 faded to orange as temperature increased. This equilibrium shift to the left suggests that the reaction is exothermic, and that heat is generated when the iron thiocyanate product is formed.
What does allyl isothiocyanate do?
It is used principally as a flavoring agent in foods. Synthetic allyl isothiocyanate is used as an insecticide, as an anti-mold agent bacteriocide, and nematicide, and is used in certain cases for crop protection.
Which of the following contains isothiocyanate glycosides?
Cruciferous vegetables, such as bok choi, broccoli, Brussels sprouts, cabbage, cauliflower, horseradish, kale, kohlrabi, mustard, radish, rutabaga, turnip, and watercress, are rich sources of glucosinolate precursors of isothiocyanates (63).
What contains allyl isothiocyanate?
Allyl isothiocyanate is generated from allyl glucosinolate (i.e., sinigrin) naturally occurring in mustard and other members of the Brassicaceae family such as the cruciferous vegetables cabbage and cauliflower. It is a main pungent compound of some relishes, such as horseradish products and mustard pastes.
