Ketoprofen USP standard (KTP), a nonsteroidal anti-inflammatory drug, was procured from ScienceLab Inc. (Houston, TX, USA). Stearic acid (SA) (USP/NF standard) was purchased from Alfa Aesar Chemicals (Tewksbury, MA, USA). Eudragit® L100 and Eudragit® L100-55, polyacrylic acids (USP/NF standard), were generously gifted by Evonik Industries AG (Essen, Germany). Other high-performance liquid chromatography (HPLC) grade solvents and analytical-grade chemical reagents were purchased from Sigma-Aldrich (St. Louis, MO, USA)
Analytical grade chemical reagents
Manufactured by Merck Group
Sourced in United States
Analytical-grade chemical reagents are high-purity chemical compounds used in various analytical and scientific applications. These reagents are designed to meet strict quality standards and specifications to ensure consistent and reliable results in laboratory settings. They are commonly used in analytical techniques such as chromatography, spectroscopy, and titration, where the purity and accuracy of the reagents are crucial for obtaining precise and reproducible data.

Analytical-grade chemical reagents were purchased from Sigma-Aldrich for laboratory studies. Methyl Orange dye (MO) was used as model dye (molecular weight: 327.34 g mol−1 with molecular formula of C14H14N3NaO3S). Fig. 1 presented chemical structure of methyl orange. Phosphoric acid (H3PO4) was used for adsorbent impregnation. Hydrochloric acid (37%) (HCl), Sodium Hydroxide (NaOH) were used for the pH adjustment. All reagents were used without further purification.Fig. 1 ![]()

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
