The objective of this study was to determine the response to increments of 2 sources of dietary fat on lactating sow and progeny performance during high ambient temperatures. Data were collected from 391 sows (PIC Camborough) from June to September in a 2,600-sow commercial unit in Oklahoma. Sows were randomly assigned to a 2 × 3 factorial arrangement of treatments and a control diet. Factors i...

Rhenium complex, [ReBr(CO)3(thf)]2-catalyzed reactions between aromatic imines and either acetylenes or α,β-unsaturated carbonyl compounds gave indene derivatives in good to excellent yields. These reactions proceed via C–H bond activation, insertion of acetylenes or α,β-unsaturated carbonyl compounds, intramolecular nucleophilic cyclization, and reductive elimination. Indene derivatives were a...

An advanced stopped-in-loop flow analysis (SILFA) is proposed for the catalytic determinations of vanadium and iron. The chemistry relies on a vanadium- or iron-catalyzed oxidative reaction of p-anisidine by bromate or hydrogen peroxide in the presence of an activator (Tiron or 1,10-phenanthlorine) to form a red dye (510 nm). Reagents for the vanadium- or iron-catalyzed reaction are well mixed ...

A bioassay of o-anisidine hydrochloride for possible carcinogenicity was conducted by administering the test chemical in feed to Fischer 344 rats and B6C3F1 mice. Groups of 55 rats of each sex and 55 mice of each sex were administered o-anisidine hydrochloride at one of the following doses, either 5,000 or 10,000 ppm for rats and either 2,500 or 5,000 ppm for mice, for 103 weeks, then observed ...

The title compound is a hydantoin derivative that has been synthesized through three-component reaction of ethyl pyruvate, p-anisidine and phenyl isocyanate. This paper provides comprehensive spectral dataset for the compound, including 1H 13C{1H} NMR, IR, HRMS, X-ray crystallography analyses. A tentative mechanism comprising two complementary pathways provided based on additional experiments w...

Hexoses and pentoses can be measured either singly or in combination, with an o-anisidine reagent. It has the advantages of a fastreactionrateand relativelylittle interference from hexoses (Amax = 660 nm) in the measurement of pentoses. A simple subtraction of absorbance attributable to glucose at the maximum for pentoses (465 nm) is sufficient for satisfactory pentose estimation in urine. The ...
