ABSTRACT
The significance and desire for preliminary testing approaches that are straightforward, quick, selective, affordable, and practical for use in the field are highlighted by the increasing enormous amounts of potentially illegal samples being seized worldwide. The "z-drugs," which include zolpidem, zopiclone, and eszopiclone, are non-benzodiazepine medications used to treat insomnia. z-drugs are short-term solutions for sleeplessness and anxiety but have a long history of abuse and misuse. The extensive list is primarily utilized for drug-facilitated crimes and drug dependence. The presumptive color spot test for z-drugs, such as zolpidem, zopiclone, and eszopiclone, has been created and validated in this study. In the preliminary identification of zolpidem, zopiclone, and eszopiclone, no color spot test has been documented as per the literature. The color spot test is the most essential and routinely used technique for identifying any unknown sample substance. The color test method was proven to provide high-quality, dependable presumptive test findings and satisfy standards for preliminary screening usage. Validation experiments demonstrate that, at room temperature, the color change is specific to the zolpidem, zopiclone, and eszopiclone classes and unaffected by the common cutting agent's presence. It was discovered that 5, 10, and 6 ppm were the operational limit of detection of the sample present against the reagents 0.1% diphenyl carbazone, aqueous potassium iodoplatinate, and modified cobalt thiocyanate reagent, respectively. The color test is immediate and validated with other substances of a similar category and 10 ppm was the operational limit of detection.
