Ninhydrin [ CAS No : 485-47-2 ]

Ninhydrin
Ninhydrin (2,2-dihydroxyindane-1,3-dione) is a chemical used to detect ammonia or primary and secondary amines. When reacting with these free amines, a deep blue or purple color known as Ruhemann's purple is produced. Ninhydrin is most commonly used to detect fingerprints, as the terminal amines of lysine residues in peptides and proteins sloughed off in fingerprints react with ninhydrin.

Murexide [ CAS No : 485-47-2 ]

Murexide
Murexide (NH4C8H4N5O6, or C8H5N5O6·NH3), also called ammonium purpurate or MX, is the ammonium salt of purpuric acid. It may be prepared by heating alloxantin in ammonia gas to 100 °C, or by boiling uramil with mercury oxide. W. N. Hartley found considerable difficulty in obtaining specimens of murexide sufficiently pure to give concordant results when examined by means of their absorption spectra, and consequently devised a new method of preparation for murexide. In this process alloxantin is dissolved in a large excess of boiling absolute alcohol, and dry ammonia gas is passed into the solution for about three hours. The solution is then filtered from the precipitated murexide, which is washed with absolute alcohol and dried. The salt obtained in this way is in the anhydrous state. It may also be prepared by digesting alloxan with alcoholic ammonia at about 78 °C; the purple solid so formed is easily soluble in water, and the solution produced is indistinguishable from one of murexide.

Dithizone [ CAS No : 60-10-6 ]

Dithizon
Dithizone is a sulfur-containing organic compound. It is a good ligand, and forms complexes with many metals such as lead and mercury.
Dithizone may be prepared by reacting phenylhydrazine with carbon disulfide, followed by reaction with potassium hydroxide.
Dithizone is used to assess the purity of human pancreatic islet preparations used for transplantation into patients with type 1 diabetes. Dithizone binds zinc ions present in the islet's beta cells, and therefore stains the islets red. Exocrine tissue also present in the preparations does not bind dithizone, and is therefore not stained.

Chloramine T [ CAS No : 7080-50-4 ]

Chloramine_T
Chloramine-T is the organic compound with the formula CH3C6H4SO2NClNa. Both the anhydrous salt and its trihydrate are known. Both are white powders. Chloramine-T is used as a reagent in organic synthesis.

The Sharpless oxyamination converts an alkene to a vicinal amino alcohol. A common source of the amido component of this reaction is chloramine-T. Vicinal amino-alcohols are important products in organic synthesis and recurring pharmacophores in drug discovery.

Alloxan Monohydrate [ CAS No : 2244-11-3 ]

Alloxan
Alloxan, sometimes referred to as alloxan hydrate, is the name of the organic compound with the formula OC(N(H)CO)2C(OH)2.
It is classified as a derivative of pyrimidine. The anhydrous derivative OC(N(H)CO)2CO is also known, as well as a dimeric derivative. These are some of the earliest known organic compounds. They exhibit a variety of biological activities.

Potassium Phthalimide [ CAS No : 1074-82-4 ]

Murexide
Potassium phthalimide is a chemical compound of formula C8H4KNO2. It is the potassium salt of phthalimide, and usually presents as fluffy, very pale yellow crystals. It can be prepared by adding a hot solution of phthalimide in ethanol to a solution of potassium hydroxide in ethanol; the desired product precipitates.
This compound is a commercially available reagent used in the Gabriel synthesis of amines.

Phthalimide [ CAS No : 85-41-6 ]

Phthalimide
Phthalimide is the organic compound with the formula C6H4(CO)2NH. It is the imide derivative of phthalic anhydride. It is a sublimable white solid that is slightly soluble in water but more so upon addition of base. It is used as a precursor to other organic compounds as a masked source of ammonia.
Phthalimide can be prepared by heating phthalic anhydride with alcoholic ammonia giving 95–97% yield. Alternatively, it may be prepared by treating the anhydride with ammonium carbonate or urea. It can also be produced by ammoxidation of o-xylene.

N-Hydroxy Phthalimide [ CAS No : 524-38-9 ]

N-Hydroxy-Phthalimide
N-Hydroxyphthalimide is the N-hydroxy derivative of phthalimide. The compound is used, inter alia, as catalyst for oxidation reactions, in particular for the selective oxidation (e. g. alkanes to alcohols) with molecular oxygen under mild conditions.
The synthesis of N-hydroxyphthalimide from phthaloyl chloride and hydroxylamine hydrochloride in the presence of sodium carbonate in aqueous solution was first reported by Lassar Cohn in 1880 (referred to as "Phthalylhydroxylamin").

Indole-3-Carbinol [ CAS No : 700-06-1 ]

Indole-3-carbinol
Indole-3-carbinol (C9H9NO) is produced by the breakdown of the glucosinolate glucobrassicin, which can be found at relatively high levels in cruciferous vegetables such as broccoli, cabbage, cauliflower, brussels sprouts, collard greens and kale.
It is also available in dietary supplements. Indole-3-carbinol is the subject of on-going biomedical research into its possible anticarcinogenic, antioxidant, and anti-atherogenic effects

Diindolylmethane [ CAS No : 968-05-4 ]

Diindolylmethane
Diindolylmethane is a compound derived from the digestion of indole-3-carbinol, found in cruciferous vegetables such as broccoli, Brussels sprouts, cabbage and kale.
The reputation of Brassica vegetables as healthy foods rests in part on the activities of diindolylmethane. Limited data from clinical studies indicate that DIM may have some benefits for patients suffering from types of prostate cancer, however more studies are required.
