Combination of TLC, GLC (OV 1 and OV 17) and HPLC (RP 18) for a rapid detection of drugs, intoxicants and related compounds was written by Daldrup, T.;Susanto, F.;Michalke, P.. And the article was included in Fresenius’ Zeitschrift fuer Analytische Chemie in 1981.Formula: C17H15NO5 The following contents are mentioned in the article:
Relative retention times for 570 drugs and related compounds on 8 chromatog. systems were reported. TLC employing silica gel plates, gas chromatog. employing 3% OV-1 on Chromosorb W-HP, and reversed-phase high-pressure chromatog. employing octadecylsilanized columns were described. This study involved multiple reactions and reactants, such as 4-Acetamidophenyl 2-acetoxybenzoate (cas: 5003-48-5Formula: C17H15NO5).
4-Acetamidophenyl 2-acetoxybenzoate (cas: 5003-48-5) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Formula: C17H15NO5
