Figure 5From: Novel spectrophotometric method for determination of cinacalcet hydrochloride in its tablets via derivatization with 1,2-naphthoquinone-4-sulphonateLimiting logarithmic plot for molar reactivity of CIN with NQS. C and A are the concentration and absorbance, respectively. For generating the first line (♦), [NQS]: 1.9 × 10-3; [CIN]: 7.6 × 10-6 - 2.5 × 10-4 M. For generating the second line (●), [NQS]: 1.9 × 10-3 - 9.6 × 10-3 M; [CIN]: 1 × 10-4M.Back to article page
