Abstract:
There is disclosed an electrochemical deblocking solution for use on an electrode microarray. There is further disclosed a method for electrochemical synthesis on an electrode array using the electrochemical deblocking solution. The solution and method are for removing acid-labile protecting groups for synthesis of oligonucleotides, peptides, small molecules, or polymers on a microarray of electrodes while substantially improving isolation of deblocking to active electrodes. The method comprises applying a voltage or a current to at least one electrode of an array of electrodes. The array of electrodes is covered by the electrochemical deblocking solution.

Abstract:
A nitro group-containing naphthoquinone derivative represented by the following general formula: ##STR1## wherein R is a monovalent hydrocarbon group having a nitro group, and a ring A may be substituted with a substituent.This compound is a novel substance and is useful as an electron-transporting agent for an electrophotosensitive material. The electrophotosensitive material using the electron-transporting agent is highly sensitive, exhibits favorable repetitive properties, and makes it possible to favorably form images for extended periods of time.
Abstract:
Compounds of the general formula ##STR1## wherein n, R.sub.1, R.sub.2 and X are defined herein, are effective inhibitors of polymerization of vinylic monomers, particularly acrylic monomers. The inhibitors are easily, efficiently, and thoroughly removed from solution with the monomer by contact with charcoal.
Abstract:
New quinone compounds of the formula: ##STR1## wherein R is methyl or methoxy andY is formyl, carboxyl, an alkoxycarbonyl having 2 to 5 carbon atoms, carbamoyl, a mono- or di- alkylcarbamoyl whose alkyl moiety has 1 to 4 carbon atoms or carbamoyloxymethyl, ortheir hydroquinone-form compounds, or pharmaceutically acceptable salts thereof, have useful physiological activities such as antiasthmatic and antiallergic activities.
Abstract:
A crude naphthoquinone produced by an oxidation of naphthalene is purified by a reduced pressure distillation of a crude 1,4-naphthoquinone having an acid content of less than 5 equivalent % calculated as monobasic acid and the crude naphthoquinone is preferably treated by an oxidation of oxidizable impurities.
