Use of palladium(II) chloride as colour-forming reagent in determination of pralidoxime chloride in water and tablets
(Journal of Pharmaceutical and Biomedical Analysis, 1988)
Pralidoxime chloride (PAM-2Cl) has been determined spectrophotometrically in Britton-Robinson buffer solution at pH = 6.45; the method is based on measurement of the absorbance of the Pd(II)-pralidoxime complex at 327 nm. ...
Acidity constants of cefetamet, cefotaxime and ceftriaxone; the effect of the substituent at C3 position
(Elsevier Science BV, Amsterdam, 2005)
Ionization constants of three cephalosporin antibiotics, cefetamet (CEF), cefotaxime (CFX) and ceftriaxone (CFTR) are determined using pH-potentiometric titrations at I= 0.1 M (NaCl) and t = 25 degrees C. Cefetarnet and ...
Multicriteria optimization methodology in development of HPLC separation of mycophenolic acid and mycophenolic acid glucuronide in human urine and plasma
(Elsevier Science BV, Amsterdam, 2009)
Multicriteria optimization methodology was applied for development of isocratic reversed-phased HPLC method for simultaneous determination of mycophenolic acid (MPA) and mycophenolic acid glucuronide (MPAG) in human urine ...

(Elsevier Science BV, Amsterdam, 2014)
Chromatography techniques such as HPTLC and HPLC are commonly used to produce a chemical fingerprint of a plant to allow identification and quantify the main constituents within the plant. The aims of this study were to ...
Development of liquid chromatographic method for the analysis of dabigatran etexilate mesilate and its ten impurities supported by quality-by-design methodology
(Elsevier Science BV, Amsterdam, 2015)
In this paper, the development of reversed-phase liquid chromatographic method for the analysis of dabigatran etexilate mesilate and its ten impurities supported by quality by design (QbD) approach is presented. The defined ...
Spectrophotometric investigation of complex formation of an oxime PAM-4Cl with palladium(II) and its analytical application
(Journal of Pharmaceutical and Biomedical Analysis, 1990)
The colour reaction of 4-hydroxyiminomethyl-1-methylpyridinium chloride (PAM-4Cl) and palladium(II) chloride has been investigated. The optimum reaction conditions, spectral characteristics, conditional stability constant ...
Application of Analytical Quality by Design concept for bilastine and its degradation impurities determination by hydrophilic interaction liquid chromatographic method
(Elsevier Science BV, Amsterdam, 2016)
This paper deals with the development of hydrophilic interaction liquid chromatographic (HILIC) method for the analysis of bilastine and its degradation impurities following Analytical Quality by Design approach. It is the ...
