The age distribution of esterases in the interstitial cell of the mouse testis was studied between birth and the end of the tenth week of postnatal life by using the substrates O-acetyl-s-bromoindoxyl, a-naphthyl acetate, naphthol AS acetate, naphthol AS-LC acetate, and naphthol AS-D acetate. With indoxyl acetate, esterase activity is prominent at birth and wanes over the first 2 weeks of postn...

The interaction of the cationic carbocyanine dye Stains-all (1-ethyl-2-[3-(1-ethyl-naphthol[1,2-d]thiazolin-2-ylidene)-2- methylpropenyl]naphthol[1,2-d]thiazolium bromide) with the eye lens proteins crystallins has been studied. alpha- and gamma-crystallins do not bind the dye, while beta- and delta-crystallins do, consistent with the fact that the latter two proteins bind the calcium ion. beta...

Abstract A homochiral metal–organic framework (MOF) comprising [Co(L)(bpe)2(H2O)2]·H2O was prepared using (1R,2R)-(−)-1,2-cyclohexanedicarboxylic acid (H2L) and 1,2-bis(4-pyridyl)-ethylene as organic ligands. The MOF explored chiral stationary phase (CSP) for high-performance liquid chromatography (HPLC) separation of racemates. Nine racemates including naphthol, alcohol, diol, amine, ketone, e...

1. 2-Amino-1-naphthyl hydrogen sulphate can be rapidly isolated from the urine of dogs dosed with 2-naphthylamine by precipitation with cetylpyridinium bromide. 2. No evidence was obtained for the presence of 2-naphthylhydroxylamine-O-sulphonic acid, noteworthy as a possible source of the carcinogens, 2-naphthylhydroxylamine and 2-amino-1-naphthol. 3. Treatment of neutral persulphate oxidations...

A solid chelating material, 1-(2-pyridy1azo)-2-naphthol (PAN) supported on naphthalene provides a rapid and highly selective means of preconcentration of uranium from aqueous solution. Uranium is quantitatively retained on this adsorbent in the pH range 9.8-10.7 with a flow rate of 1 ml min . The metal complex was desorbed with 10 ml of 2 M hydrochloric acid and uranium is determined by d...

Excited-state proton transfer from 5,8-dicyano-2-naphthol to methanol takes place in CO2/methanol mixtures, in the pressure and temperature ranges of supercritical CO2. The efficiency of the proton-transfer step decreases with the pressure. This is assigned to the perturbation of the methanol clusters solvating the naphthol.

We used second harmonic generation (SHG) spectroscopy to study the chiroptical properties of R -, S - and racemic ( RAC -) 1,1′-bi-2-naphthol (BINOL) films with various thicknesses, incidence angles degrees crystallization in film.
