In addition, N,N ′-diisopropylurea, its byproduct in many chemical reactions, is soluble in most organic solvents, a property that facilitates work-up. Safety [ edit ]
Allied Corp. was a major American company with operations in the chemical, aerospace, automotive, oil and gas industries. It was initially formed in 1920 as the Allied Chemical and Dye Corporation as an amalgamation of five chemical companies. In 1958, it was renamed Allied Chemical Corporation when it diversified into oil and gas exploration.
The journal was established in 1909 as the Journal of Industrial & Engineering Chemistry. It was renamed in 1930 as Industrial & Engineering Chemistry before obtaining its current title in 1970. From 1911 to 1916 it was edited by Milton C. Whitaker. From 1921 to 1942 it was edited by Dr. Harrison E. Howe. [1]

Unichem Laboratories was founded in 1944 by Padma Bhushan Amrut V Mody, a pioneer in the Indian pharmaceuticals business.. The initial public offering of Unichem Laboratories Limited was in 1963, after its registration in 1962, [4] and the company was consequently listed on BSE Limited and NSE Limited.
DIPEA is a sterically hindered organic base that is commonly employed as a proton scavenger. Thus, like 2,2,6,6-tetramethylpiperidine and triethylamine, DIPEA is a good base but a poor nucleophile, DIPEA has low solubility in water, which makes it very easily recovered in commercial processes, a combination of properties that makes it a useful organic reagent.
