Method development and validation of potent pyrimidine derivative by UV-VIS spectrophotometer
BACKGROUND A rapid and sensitive ultraviolet-visible (UV-VIS) spectroscopic method was developed for the estimation of pyrimidine derivative 6-Bromo-3-(6-(2,6-dichlorophenyl)-2-(morpolinomethylamino) pyrimidine4-yl) -2H-chromen-2-one (BT10M) in bulk form. RESULTS Pyrimidine derivative was monitored at 275 nm with UV detection, and there is no interference of diluents at 275 nm. The method was...
متن کاملAdvantages of Photo Diode Array for UV-Vis Spectrophotometer
1 Preface All products are continuously being improved for better performance. Spectrometers have developed in many ways since the introduction of simple and moderately priced Spectrophotometers which were commercially available from the mid 1950’s. 1 Such improvements have enabled SCINCO to manufacture PDA type UV-Vis. Spectrophotometers. The scope and performance of conventional single channe...
متن کاملOptofluidic UV-Vis spectrophotometer for online monitoring of photocatalytic reactions
On-chip integration of optical detection units into the microfluidic systems for online monitoring is highly desirable for many applications and is also well in line with the spirit of optofluidics technology-fusion of optics and microfluidics for advanced functionalities. This paper reports the construction of a UV-Vis spectrophotometer on a microreactor, and demonstrates the online monitoring...
متن کاملSubcritical Butane Extraction of Wheat Germ Oil and Its Deacidification by Molecular Distillation.
Extraction and deacidification are important stages for wheat germ oil (WGO) production. Crude WGO was extracted using subcritical butane extraction (SBE) and compared with traditional solvent extraction (SE) and supercritical carbon dioxide extraction (SCE) based on the yield, chemical index and fatty acid profile. Furthermore, the effects of the molecular distillation temperature on the quali...
متن کاملGabapentin Determination in Human Plasma and Capsule by Coupling of Solid Phase Extraction, Derivatization Reaction, and UV-Vis Spectrophotometry
Gabapentin is an anticonvulsant widely used in the treatment of epilepsy. No peculiar chromophore is available on the gabapentin moiety for direct analysis by absorption spectrophotometry. A sensitive spectrophotometric method for the determination of gabapentin in bulk, pharmaceutical formulations and human plasma has been developed. In this method, gabapentin directly derivatized with vanilli...
