3-Benzoylpropionic Acid f 3.55 5g. C (! H5COCH L ,CH 2 COOH 25 g. 13.10 Chemical intermediate in the formation of 4-cyclohexylbutyric acid, 4-phenylbutyric acid, 3-benzoylpropionanilide (J. Org. Chem. 26, 2127, 1961; Ann. Chim. 51, 283, 1961). Demon strates some antimicrobial activity in yeasts, molds, bacteria (Biologia [Bratislava] 16, 905, 1961) as well as flower induction and inhibition in the pineapple plant (Bot. Gaz. 121, 143, 1960).

Detection reagent for streptomycin as based on a 1947 method reported in J. Biol. Chem. 170, 491, 1947. This compound as sumes the form of pale yellow needles in the crystalline state, is soluble in cold ethanol and Ν-acetic acid, turns intense orange and scarlet color in ethanolic solutions with benzaldehyde and p-nitrobenzaldehyde, exhibits a melting-point range of 168 to 172 degrees (J. Chem. Soc. 4653, 1965). 1,2,4-Tribromobenzene 25 g. . . $ 2.90 C(iH:iBr:i 100 g. . . 8.50 High-density, low-melting solid. Suggested for making highdensity liquids by mixing with other low-melting-point, highdensity compounds. Confirmation of the unprecedented isomerization of 1,2,4-tribromobenzene to 1,3,5-tribromobenzene is re ported in J.A.C.S. 85, 1891, 1963.
2-(l,3-Dioxolan-2-yl) Pyridine 25 g. .$ 8.95 Ν : CHCH : CHCH : CCHOCH2CH20
32.40 100 1 For cyclodehydration reactions leading to acridizinium salts. Produces higher quality compounds with better yields than pre viously used picolinaldehyde derivatives (J. Org. Chem. 28, 83, 1963).
I 4.25 2-Iodoacetamide 5g. ICH.CONH·, 16.55 25 g. Electrophoretic studies of plasma proteins reveal that treatment of proteins with this substance results in characteristic changes in the mobilities of certain components (Biochem. J. 74, 4 4 P , 1960). Various aspects of this compound have inspired an ex tensive literature. EASTMAN 10269
Tetramethylammonium Nitrate j c „ S10 40 (CH :! )jNNO :! 100 g. '.'. 3835 Electroinitiated polymerization of styrene is accomplished with this substance, one of a number of tetramethylammonium salts successfully employed for this procedure. High electrical effi ciencies and molecular weights from 15,000 to 50,000 confirm success of the methodology (Can. J. Chem. 42, 2733, 1964).
