Selenium Sulphide also known as Selenium Disulphide is an Inorganic compound having the formula Se S2., Mol.wt. 143.08 , CAS No. 7488-56-4 . Selenium Sulphide compound is a mixture with the overall Se:S ratio 1:2. Selenium Sulphide is Reddish brown to orange colored solid available in micronized powder form. Selenium sulphide is not soluble in Water but soluble in Carbon disulphide. Selenium Sulphide finds its main applications as an anti-fungal agent used in the shampoos for the treatment of dandruff or seborrhea of the scalp which is also called as seborrheic dermatitis of the scalp . The dandruff in hair is caused due to shedding of dead skin from the scalp and regeneration of new skin or can be due to a fungal infection . For the treatment of such fungal infection in the scalp ,these shampoos are found to be very effective .

3,5-Diiodosalicylic Acid is used in wide range of medicals industrial applocations as well as in human and animal nutrition products such as antiseptics and disinfectants, pharmaceutical intermediates, polarizing films for liquid crystal display [LCD] chemicals. Iodine derivatives are also used as organic building blocks, analytical reagents etc. 3,5-Diiodosalicylic Acid appears like white to creamy white powder, and has range of melting point 232-238°C. 3,5-Diiodosalicylic Acid has a CAS No 133-91-5 and has Molecular Formula C7H4I2O3. Its Molecular weight is 389.91.

Potassium Iodide is known as Potassium Salt of Hydriodic Acid [HI], available in white crystalline powder form. It is an inorganic compound and has Molecular Formula KI. Its Ionic form is K+ I-, and iodide ion being mild reducing agent, it can be easily oxidized to Iodine by powerful oxidizing agent like chlorine. With elemental iodine it forms I3 (tri iodide), the salts of tri iodide are highly water soluble. On long exposure to air Potassium Iodide becomes yellow due to liberation of Iodine. Potassium Iodide is more readily soluble in water. The solubility in water increases with the increase in temperature ie. (140 gms. 100 ml @ 20°c, 206 gms 100 ml @ 100°c). It is slightly soluble in ether, ammonia. It absorbs water less readily than Sodium Iodide and hence convenient to use. It is produced industrially by treating Iodine with Potassium Hydroxide. It can also be prepared by the action of Potassium Bicarbonate on Hydriodic acid. It finds its applications mainly in organic synthesis for the preparation of Aryl iodides [Sandmeyer Reaction] from Aryl amine. Aryl amines are first diazotized by the action of Nitrous acid to obtain Arene diazonium salts which are then iodinated by using Potassium iodide to obtain Aryl Iodide.

We are offering methyl iodide. Methyl iodide is also called iodomethane having molecular formula ch3i, mol. Wt. 141.94 gmol. It is an important halo alkane derivative of methane, in which one atom of hydrogen in methane is replaced by one atom of iodine. Methyl iodide is an organo iodine compound that contains one carbon – iodine bond. Iodomethane contains methyl group, with formula ch3 (also called me). In methyl iodide it exists as methylium cation ( ch3+) which is obtained by protonation of methanol. Methyl iodide is highly reactive, the methylium cation acts as a strong electrophillic methylating agent, while the iodide ion is a powerful nucleophile and is a good leaving group. Methyl iodide is a dense, colorless, volatile liquid turns brown on exposure to light due to liberation of iodine. Methyl iodide has a very low boiling point (b.p. 41-43 °c), sp. Gr. At 20 °c: 2.27 – 2.28gmcc. Iodomethane is slightly soluble in water, miscible with alcohol, ether. Being an organo iodide compound, methyl iodide is sensitive to light and therefore needs to be stored in dark amber colored bottles to prevent its degradation by light. Iodomethane is stabilized by copper or silver wire. Methyl iodide is prepared by any one of the following methods : by the reaction of iodine on mixture of methanol and red phosphorous. By the reaction of dimethyl sulphate with potassium iodide by the reaction of methanol with potassium iodide catalyzed by acid. It finds its main applications : in the organic synthesis as a methylating agent for methylation of carboxylic acids ,phenols. Methyl iodide is used in the preparation of tetra methyl ammonium hydroxide iodomethane is used in the preparation of methyl magnessium iodide (grignard reagent). As a pesticide(v) for preplant soil treatment in the fields of strawberries , peppers, tomatoes.

We manufacture a range of Organic, Inorganic and Organo Inorganic Intermediates. The Inorganic Intermediates include Selenium derivatives, Iodine derivatives and the organic intermediates include Tartaric acid derivatives and other intermediates

CAS No. : 1306-24-7

Ammonium molybdate is an odorless crystalline compound ranging in color from white to yellow-green. Also called molybdic acid hexammonium salt tetrahydrate, ammonium molybdate tetrahydrate and ammonium heptamolybdate tetrahydrate. In chemistry a Ammonium molybdate is a compound containing an oxoanion with molybdenum in its highest oxidation state of 6. Ammonium molybdate can form a very large range of such oxoanions which can be discrete structures or polymeric extended structures, although the latter are only found in the solid state. The discrete Ammonium molybdate oxoanions range in size from the simplest MoO42−, found in potassium molybdate up to extremely large structures found in isopoly-molybdenum blues that contain for example 154 Mo atoms.
