一般描述
Potassium phthalate monobasic is the monopotassium salt of phthalic acid. It has been proposed as a certified reference material (CRM) under ISO/IEC 17025 and ISO Guide 34 accreditation. Its spectral shift, multiplicity, solubility and relaxation times in different solvents have been reported.
应用
Potassium phthalate monobasic may be used as a buffer to maintain pH = 2.39 and 4.52, during the dispersive ionic liquid-liquid microextraction coupled with liquid chromatography and UV detection of drug (benznidazole and nifurtimox) levels in human plasma. It has been used as internal standard certified reference material (CRM) for the high performance (HP)-quantitative NMR spectroscopic (qNMR) determination of various organic compounds.

Dispersive ionic liquid-liquid microextraction combined with liquid chromatography and UV detection was used for the determination of two antichagasic drugs in human plasma: nifurtimox and benznidazole. The effects of experimental parameters on extraction efficiency-the type and volume of ionic liquid

Previous studies suggest that prenatal phthalate exposure affects neurodevelopment and behavior during the first years of life. To evaluate the effect of maternal urinary concentrations of phthalate metabolites during pregnancy on mental and psychomotor development in children 24-36 months of

High-molecular-weight phthalates in indoor dust have been associated with asthma in children, but few studies have evaluated phthalate biomarkers in association with respiratory outcomes. We explored the association between urinary concentrations of phthalate metabolites and current asthma. In a cross-sectional

Baleen whales are potentially exposed to micro-litter ingestion as a result of their filter-feeding activity. However, the impacts of microplastics on baleen whales are largely unknown. In this case study of the Mediterranean fin whale (Balaenoptera physalus), we explore the

Phthalates have been used for decades in large quantities, leading to the ubiquitous exposure of the population. In an investigation of 63 German daycare centers, indoor air and dust samples were analyzed for the presence of 10 phthalate diesters. Moreover
