Product Name: Dimethyl Sulfoxide Other Name: sulfinylbis (methane);DMSO;DIMETHYL SULFOXIDE;DIMETHYL SULPHOXIDE Molecular Formula: C2H6OS Molecular Weight: 78.13 Appearance: Corlorless liquid or corlorless crystals Purity: 99% CAS Number: 67-68-5 EINECS number: 200-664-3 Supplier: ZHENYIBIO Dimethyl sulfoxide (abbreviated DMSO) is a sulfur-containing organic compound; molecule formula: (CH3) 2SO; It exhibits as colorless, odorless, hygroscopic and flammable transparent liquid at room temperature. It has both high polarity as well as high-boiling point. It also has aprotic and water-miscible characteristics. It has low toxicity, good thermal stability, and is not miscible with paraffin. It is soluble in water, ethanol, propanol, ether, benzene and chloroform and many other kinds of organic substance and is called as the "universal solvent." It is a common organic solvent which has the strongest dissolving ability. It can dissolve most the organic compounds including carbohydrates, polymers, peptides, as well as many inorganic salts and gases. It can dissolve certain amount solute whose weight is equals to 50-60% of itself (other common solvents usually only dissolve 10-20%), so it is very important in the sample management as well as high-speed screening of drugs. Under certain conditions, contact between dimethyl sulfoxide and chloride can even lead to explosive reaction.

FH SERIES OF PRODUCTS: FH products are Pure nonionic derived the endosperm of guar polysaccharide (Cyamopsos tetragonolobus). The products are unique with ultra-high viscosity with fastest hydration characteristics as shown in Figure 1 below. Also, when added with other drilling components, to seawater, a KCl solution or other aqueous system, the product suspension disperses readily without lumping, even under low-shear conditions generating most of its full viscosity within just a few minutes. PRODUCT COMPATIBILITY: FH series of products are compatible with most of the chemicals and auxiliaries used in drilling operations. However, the products are not compatible with Arabic and Crystal gums. Also, in presence of borates they form elastic gel. PRODUCT APPLICATIONS: FH series of products are natural, high viscosity, fast hydrating non-Newtonian hydrocolloids with suitable cross linking components in diesel slurries and are versatile for continuous mix applications, where extremely fast hydration and subsequent viscosity development is required. They are excellent viscosifiers, stabilizers, thickeners and suspending agent for use in oil-drilling, workover fluids and several other oilfield applications like hydraulic fracturing, oil well stimulation, mud drilling, oil well capping, flocculent and liquid shoring etc. The product is used as a surfactant; synthetic polymer and deformer ideally suited for all rheological requirements of water based and brine based drilling fluids.
