Figure 7From: Novel spectrophotometric method for determination of cinacalcet hydrochloride in its tablets via derivatization with 1,2-naphthoquinone-4-sulphonateLinear plot for log C versus log K for the kinetic reaction of CIN with NQS. C is the CIN concentration (7.6 × 10-6 - 2.5 × 10-4 M) and K is the reaction rate (second-1).Back to article page
