Simon's reagent is used as a simple spot-test to presumptively identify alkaloids as well as other compounds. It reacts with secondary amines like MDMA and methamphetamine to give a blue solution. Uses
The above photo shows the positive results of the number 2 Marquis reagent presumptive drug test when used with a sample of opium. It is the primary presumptive test used in Ecstasy reagent testing kits. It can also be used to test for such substances as opiates (e.g. codeine, heroin), and phenethylamines (e.g. 2C-B, mescaline).
Adderall and Mydayis [11] are trade names [note 2] for a combination drug containing four salts of amphetamine. The mixture is composed of equal parts racemic amphetamine and dextroamphetamine , which produces a (3:1) ratio between dextroamphetamine and levoamphetamine , the two enantiomers of amphetamine. [ 13 ]
Amphetamine is a weak base with a pK a of 9.9; [3] consequently, when the pH is basic, more of the drug is in its lipid soluble free base form, and more is absorbed through the lipid-rich cell membranes of the gut epithelium. [3] [29] Conversely, an acidic pH means the drug is predominantly in a water-soluble cationic (salt) form, and less is ...
The false positive rate is equal to the significance level. The specificity of the test is equal to 1 minus the false positive rate. In statistical hypothesis testing, this fraction is given the Greek letter α, and 1 − α is defined as the specificity of the test. Increasing the specificity of the test lowers the probability of type I errors ...
Two common trade brands for ADHD medication, Adderall and Concerta are made from different drug formulas. Adderall is made from amphetamine mixed salts and Concerta is made from methylphenidate.
Amid ongoing ADHD drug shortages, Adderall supplies have improved, but other brand name and generic medications such as Ritalin are still hard to come by, doctors say.
Reagent testing is one of the processes used to identify substances contained within a pill, usually illicit substances. With the increased prevalence of drugs being available in their pure forms, the terms "drug checking" or "pill testing" [1] may also be used, although these terms usually refer to testing with a wider variety of techniques covered by drug checking.
