Thermally induced solid-state transformation of cimetidine. A multi-spectroscopic/chemometrics determination of the kinetics of the process and structural elucidation of one of the products as a stable N3-enamino tautomer
(Elsevier Science, 2015-05)
Exposure of cimetidine (CIM) to dry heat (160-180 °C) afforded, upon cooling, a glassy solid containing new and hitherto unknown products. The kinetics of this process was studied by a second order chemometrics-assisted ...
Unveiling meloxicam monohydrate process of dehydration by an at-line vibrational multi-spectroscopy approach
(Elsevier Science, 2021-08)
Meloxicam (MLX) is a non-steroidal anti-inflammatory drug, extensively used for inflammatory diseases and pain treatments, which exhibits five known solids forms. Form IV of MLX, a zwitterionic monohydrate (MH), is an ...
A chemometric approach for determining the reaction quantum yields in consecutive photochemical processes
(Royal Society of Chemistry, 2017-08)
A chemometric procedure to deal with spectroscopically monitored processes involving photochemical steps is fully described. The methodology makes it possible to work with reactions that involve several components with ...

El fraude alimentario constituye una problemática global que no sólo afecta la economía sino también la salud y confianza del consumidor. El ajo en polvo es una especia susceptible a la adulteración con sustancias de bajo ...
The INTERPRET Decision-Support System version 3.0 for evaluation of Magnetic Resonance Spectroscopy data from human brain tumours and other abnormal brain masses
(SpringerEstados Unidos, 2010)
Background: Proton Magnetic Resonance (MR) Spectroscopy (MRS) is a widely available technique for those
clinical centres equipped with MR scanners. Unlike the rest of MR-based techniques, MRS yields not images but
spectra ...
