Bioallethrin
Bioallethrin is a brand name for an ectoparasiticide. It consists of two of the eight stereoisomers of allethrin I in an approximate ratio of 1:1. The name ''Bioallethrin'' is a registered trademark of Sumitomo Chemical. ''Esbiothrin'' (CAS number ) is a mixture of the same two stereoisomers, but in an approximate ratio of ''R'':''S'' = 1:3. ''Esbioallethrin'' or ''S-bioallethrin'' (CAS number ) is the pure ''S''-form (that is, the wedge in the structure as shown in the box points down). The name bioallethrin is a common name approved by the British Standards Institution and published in. It is also included in British Approved Names 2017 and earlier editions.

Allethrin
The allethrins are a group of related synthetic compounds used in insecticides. They are classified as pyrethroids, i.e. synthetic versions of pyrethrin, a chemical with insecticidal properties found naturally in ''Chrysanthemum'' flowers. They were first synthesized in the United States by Milton S. Schechter in 1949. Allethrin was the first pyrethroid. They are commonly used in ultra-low volume sprays for outdoor mosquito control, and in many household insecticides such as Raid (insecticide), RAID, as well as mosquito coils. Chemical structure Allethrin I and allethrin II differ by having a methyl group and a methyl ester, respectively, on one terminus. Each of these allethrins consists of the eight possible stereoisomers. A partly enantiopure variant of allethrin I, consisting of only two stereoisomers in an approximate ratio of 1:1, is called bioallethrin. The same mixture of isomers, but in an approximate ratio of 3:1, is known as esbiothrin. Toxicity Chronic exposure to al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brand
A brand is a name, term, design, symbol or any other feature that distinguishes one seller's good or service from those of other sellers. Brands are used in business, marketing, and advertising for recognition and, importantly, to create and store value as brand equity for the object identified, to the benefit of the brand's customers, its owners and shareholders. Brand names are sometimes distinguished from Generic brand, generic or store brands. The practice of branding - in the original literal sense of marking by burning - is thought to have begun with the ancient Egyptians, who are known to have engaged in livestock branding as early as 2,700 BCE. Branding was used to differentiate one person's cattle from another's by means of a distinctive symbol burned into the animal's skin with a hot branding iron. If a person stole any of the cattle, anyone else who saw the symbol could deduce the actual owner. The term has been extended to mean a strategic personality for a produ ...

Ectoparasiticide
An ectoparasiticide is an antiparasitic drug used in the treatment of ectoparasitic infestations. These drugs are used to kill the parasites that live on the body surface. Permethrin, sulfur, lindane, dicophane, benzyl benzoate, ivermectin and crotamiton Crotamiton is a drug that is used both as a scabicidal (for treating scabies) and as a general antipruritic (anti-itching drug). It is a prescription, lotion-based medicine that is applied to the whole body to get rid of the scabies parasite that ... are well known ectoparasiticides. Permethrin Broad-spectrum and potent pyrethroid insecticide and is most convenient for both scabies and lice. First choice drug. 100% cure rate. Causes neurological paralysis in insects probably by delaying depolarisation. Crotamiton Second choice drug. Effective scabicide, pediculocide and antipruritic. Cure rate 60-88%. Benzyl benzoate 2nd line drug for scabies and is seldom used for pediculosis. Cure rate 76-100% Lindane Effective in trea ...

Stereoisomer
In stereochemistry, stereoisomerism, or spatial isomerism, is a form of isomerism in which molecules have the same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space. This contrasts with structural isomers, which share the same molecular formula, but the bond connections or their order differs. By definition, molecules that are stereoisomers of each other represent the same structural isomer. Enantiomers Enantiomers, also known as optical isomers, are two stereoisomers that are related to each other by a reflection: they are mirror images of each other that are non-superposable. Human hands are a macroscopic analog of this. Every stereogenic center in one has the opposite configuration in the other. Two compounds that are enantiomers of each other have the same physical properties, except for the direction in which they rotate polarized light and how they interact with different optical isom ...

Trademark
A trademark (also written trade mark or trade-mark) is a type of intellectual property consisting of a recognizable sign, design, or expression that identifies products or services from a particular source and distinguishes them from others. The trademark owner can be an individual, business organization, or any legal entity. A trademark may be located on a package, a label, a voucher, or on the product itself. Trademarks used to identify services are sometimes called service marks. The first legislative act concerning trademarks was passed in 1266 under the reign of Henry III of England, requiring all bakers to use a distinctive mark for the bread they sold. The first modern trademark laws emerged in the late 19th century. In France, the first comprehensive trademark system in the world was passed into law in 1857. The Trade Marks Act 1938 of the United Kingdom changed the system, permitting registration based on "intent-to-use", creating an examination based process, an ...

CAS Number
A CAS Registry Number (also referred to as CAS RN or informally CAS Number) is a unique identification number assigned by the Chemical Abstracts Service (CAS), US to every chemical substance described in the open scientific literature. It includes all substances described from 1957 through the present, plus some substances from as far back as the early 1800s. It is a chemical database that includes organic and inorganic compounds, minerals, isotopes, alloys, mixtures, and nonstructurable materials (UVCBs, substances of unknown or variable composition, complex reaction products, or biological origin). CAS RNs are generally serial numbers (with a check digit), so they do not contain any information about the structures themselves the way SMILES and InChI strings do. The registry maintained by CAS is an authoritative collection of disclosed chemical substance information. It identifies more than 182 million unique organic and inorganic substances and 68 million protein and DNA seq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
