Concomitant positive reactions to colophonium, oxidized limonene, and/or oxidized linalool are recorded in patch test studies. The main allergens in these patch test mixtures are hydroperoxides, which form antigens by a radical pathway. Theoretically, concomitant reactions can be explained not

A new class of thermally activated chain-breaking antioxidants is presented. Dimers of persistent carbon-centered radicals are able to inhibit the autoxidation of cumene and styrene with better rate constants than the commercial antioxidant Irganox HP-136 and 3,5-di-tert-butyl-4-hydroxyanisole. A dramatic increase

To emphasize the fact that solvents can be either critical or immaterial in crystallizing specific polymorphs, a method for obtaining multiple polymorphs of a compound using only one solvent is demonstrated. By varying the crystallization temperature and level of supersaturation

The meta-cleavage product hydrolase from Pseudomonas fluorescens IP01 (CumD) hydrolyzes 2-hydroxy-6-oxo-7-methylocta-2,4-dienoate (6-isopropyl HODA) in the cumene (isopropylbenzene) degradation pathway. To modulate the substrate specificity and catalytic efficiency of CumD toward substrates derived from monocyclic aromatic compounds, we constructed the CumD

The antioxidant effects of the new thiosulfinate derivative, S-benzyl phenylmethanethiosulfinate (BPT), against the oxidation of cumene and methyl linoleate (ML) in chlorobenzene were studied in detail using HPLC. The results showed that BPT provided effective inhibition with a well-defined induction
