4-nitro-4-[N-ethyl-N-(2-hydroxyethyl)-amino]azobenzene acrylate (C H N O ) containing an acryloxy ' 19 20 4 4 group, first 4-nitro-4-[N-ethyl-N-(2-hydroxyethyl)-amino]azobenzene was prepared by reacting 4' nitrobenzenediazonium salt with N-ethyl-N-hydroxy ethylaniline and then its acryloxyloxy derivative was synthesized in a Schoten-bauman type reaction. The characterization of the synthesized ...

A cleavable azo linker was synthesized and reacted with 5-(6)-carboxytetramethyl rhodamine succinimidyl ester, followed by further reactions with di(N-succinimidyl) carbonate and 5-(3-amino-1-propynyl)-2'-deoxyuridine 5'-triphosphate [dUTP(AP3)] to obtain the terminal product dUTP-azo linker-TAMRA as a potential reversible terminator for DNA sequencing by synthesis with no need for 3'-OH blocking.

this research is an attempt to measure the effect of alkyl tail on the visible spectra and order parameters s of some azo n-ester-1,8-naphthalimide(anen) disperse dyestuff. for the first time, the visible absorption spectra of two azo n-ester-1,8-naphthalimide(anen) dyes with identical molecular size and diverse alkyl tails were obtained in liquids and liquid crystalline solvent. ordinary organ...

The coupling of aromatic diazo compounds with compounds containing a reactive methylene group to form 'mixed' azo compounds (tautomeric with hydrazones) was recognized as a general reaction following Meyer's (1877) synthesis of phenylazoacetoacetic ester from benzenediazohydroxide and ethyl acetoacetate. Japp & Klingemann (1888) found that when equimolar amounts of acetoacetic acid and benzened...

(1) Proteolytic digests of tissue elastin contain material which reacts with dimethylaminobenzaldehyde in acid solution (Ehrlich's reagent) to give a cherry-pink colour. This Ehrlich chromogen(s) [EC(s)] is similar to but not identical with EC(s) previously demonstrated in tissue collagens [Scott, Hughes & Shuttleworth (1979) Biosci. Rep. 1, 611-618]. Both ECs react with diazonium salts in acid...

Different binary phase diagrams, made from two differently substituted three-rings azo/ester and azomethine/ester compounds of the same terminal alkoxy side chain six carbons, as opposed to other polar substituent, which can either donate electrons or withdraw including H. The thermal behavior prepared derivatives was investigated by differential scanning calorimetry phases identified polarized...
