Dimidium bromide is an inhibitor of L-cell growth. Dimidium Bromide is used as an intercalating probe for nucleic acids.

 The reaction involves the readily isolated intermediate iminochloride which undergoes facile cyclization only in presence of certain inorganic halide catalysts. The analogy to the Friedel-Crafts reaction is discussed.

DMSO (Dimethyl Sulfoxide) is a polar, aprotic organic solvent that is commonly used as a cryoprotectant because of its membrane penetrating and water displacement properties. It is added to cell culture media to reduce ice formation and thereby prevent cell death during the freezing process.

The methyl groups of DMSO are only weakly acidic, with a pKa = 35. For this reason, the basicities of many weakly basic organic compounds have been examined.

Pentetic acid or diethylenetriaminepentaacetic acid (DTPA) is an aminopolycarboxylic acid consisting of a

diethylenetriamine backbone with five carboxymethyl groups. The molecule can be viewed as an expanded version of EDTA and is used similarly. 

It is a white solid with limited solubility in waterPentetic acid or diethylenetriaminepentaacetic acid (DTPA) is an aminopolycarboxylic acid consisting of a

dimethylformamide is (CH3)2NC(O)H and is abbreviated as DMF. It is a colorless liquid which dissolves in water and most of the organic chemicals. In its purest form it is odorless and with contamination or impurities it develops a fishy odor.

The dimethylformamide-dimethyl sulfate complex prepared above is transferred to the dropping funnel and added slowly.

Natural tartaric acid is an organic acid present in some fruits and widely used in the food and wine industry. It is also used as an additive in certain foods such as baby milk, sweets, jams and fruit juices. Europe accounts for 86% of world production of natural tartaric acid, producing around 30 000 tonnes per year.

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.

The primary use of DMF is as a solvent with low evaporation rate. ... It is a common solvent in the Heck reaction. It is also a common catalyst used in the synthesis of acyl halides, in particular the synthesis of acyl chlorides from carboxylic acids using oxalyl or thionyl chloride.

Filtered through 0.2 µ filters.Reaction with sodium hydride gives exothermic decomposition at low temperatures. Keep container tightly closed in a dry and well-ventilated place.

The solvent diethylene glycol monoethyl ether (DEGEE) is currently used in over 500 cosmetic products and has enabled the formulation of a topical 5% dapsone gel for the treatment of acne

Keep container tightly sealed. Store in cool, dry conditions in well sealed containers. Incompatible with oxidizing agents. It is hygroscopic in nature. Store under dry inert gas.
