No true Scotsman, or appeal to purity, is an informal fallacy in which one attempts to protect their universal generalization from a falsifying counterexample by excluding the counterexample improperly. Rather than abandoning the falsified universal generalization or providing evidence that would disqualify the falsifying counterexample, a slightly modified generalization is constructed ad-hoc to definitionally exclude the undesirable specific case and counterexamples like it by appeal to rhetoric. This rhetoric takes the form of emotionally charged but nonsubstantive purity platitudes such as "true, pure, genuine, authentic, real", etc.
A purity test is a self-graded survey that assesses the participants' supposed degree of innocence in worldly matters, generally on a percentage scale with 100% being the most and 0% being the least pure. Online purity tests were among the earliest of Internet memes, popular on Usenet beginning in the early 1980s. However, similar types of tests circulated under various names long before the existence of the Internet.
A reagent is a substance or compound added to a system to cause a chemical reaction, or added to test if a reaction occurs. The terms reactant and reagent are often used interchangeably—however, a reactant is more specifically a substance consumed in the course of a chemical reaction. Solvents, though involved in the reaction mechanism, are usually not called reactants. Similarly, catalysts are not consumed by the reaction, so they are not reactants. In biochemistry, especially in connection with enzyme-catalyzed reactions, the reactants are commonly called substrates.
A pharmacopoeia, pharmacopeia, or pharmacopoea, in its modern technical sense, is a book containing directions for the identification of compound medicines, and published by the authority of a government or a medical or pharmaceutical society.
The one-drop rule is a social and legal principle of racial classification that was prominent in the 20th century in the United States. It asserted that any person with even one ancestor of black ancestry is considered black. It is an example of hypodescent, the automatic assignment of children of a mixed union between different socioeconomic or ethnic groups to the group with the lower status, regardless of proportion of ancestry in different groups.

Purity is an essential aspect of Islam. It is the opposite of najāsa, the state of being ritually impure. It is achieved by first removing physical impurities from the body, and then removing ritual impurity by means of wudu (usually) or ghusl.
The Temple Scroll is the longest of the Dead Sea Scrolls. Among the discoveries at Qumran it is designated: 11QTemple Scrolla. It describes a Jewish temple, along with extensive detailed regulations about sacrifices and temple practices. The document is written in the form of a revelation from God to Moses, thereby with the intended meaning that this is the more appropriate temple which was revealed to Moses, and that Moses' instructions were either forgotten or ignored when Solomon built the First Temple in Jerusalem. In other words, in the mind of the Scroll writer, "Solomon should actually have built the First Temple as it is described here in the Temple Scroll".

Responsible drug use maximizes the benefits and reduces the risk of negative impact psychoactive drugs cause on the lives of the user. For illegal psychoactive drugs that are not diverted prescription controlled substances, some critics believe that illegal recreational use is inherently irresponsible, due to the unpredictable and unmonitored strength and purity of the drugs and the risks of addiction, infection, and other side effects.
In politics, a purity test is a rigid standard on a specific issue by which a politician or other figure compared. Purity tests are established to ensure that the subject maintains ideological purity with the ideas supported by a particular group, often a political party or one specific faction of a party. Purity tests are often used in the form of strict in-group and out-group boundaries, where failure of purity tests indicates membership of an out-group. When used in this fashion, purity tests are a form of no true Scotsman fallacy. Purity tests are similar to the concept of litmus tests that are used in political nominations and appointments.
