dichlorodiphenyldichloroethyleneA long-lasting chemical that forms when the pesticide DDT breaks down. It doesn’t easily degrade, can build up in living organisms, and is known for disrupting hormones and persisting in the environment for a long time.
dichlorodiphenyltrichloroethaneA long-lasting synthetic insecticide formerly used to kill mosquitoes and crop pests. It became controversial because it persists in the environment and harms wildlife by building up in food chains.
dichloroethaneEither of two isomeric organochlorides with the molecular formula C₂H₄Cl₂: 1,1-dichloroethane (ethylidene dichloride) and 1,2-dichloroethane (ethylene dichloride).
dichloroetheneAny of several isomeric organochlorides with the molecular formula C₂H₂Cl₂.
dichloroethyleneAny of several isomeric organochlorides with the molecular formula C₂H₂Cl₂, dichloroethene.
dichlorofluoresceinA chlorinated derivative of fluorescein formed from dichlorodihydrofluorescein when used as an indicator of peroxynitrite formation
dichlorofluorescinA chemical compound, C₂₀H₁₀Cl₂O₅. that is commonly used as a fluorescent probe because it is converted to a fluorescent compound when it reacts with reactive oxygen species (ROS).
dichlorofluoromethaneA particular halomethane or hydrochlorofluorocarbon, a colourless and odourless gas used as a propellant and refrigerant, harmful to the ozone layer.
dichloronorlichexanthoneA two chlorine derivative of norlichexanthone, (IUPAC name n,m-dichloro-1,3,6-trihydroxy-8-methylxanthen-9-one) (chlorine atoms can be in position n and m of 2,4,5, or 7 depending on the isomer)
dichlorophenylAny dichloro derivative of a phenyl radical
dichlorophenylphosphineAn organophosphorus compound commonly used in the synthesis of elaborated phosphine ligands for coordination chemistry.
dichlorophosphateThe compound, functional group or anion derived from phosphate with two oxygen atoms substituted by two chlorine atoms and one sulfur atom: PO₂Cl₂⁻ or -OPOCl₂
dichlorothiophosphateThe compound or anion derived from phosphate with three oxygen atoms substituted by two chlorine atoms and one sulfur atom: POSCl₂⁻
dichlorvosA highly volatile organophosphate, 2,2-dichlorovinyl dimethyl phosphate (DDVP), widely used as a fumigant to control household pests and to protect stored product from insects.
dichotomizationThe act of dichotomizing or the thing dichotomized; classification into 2 subsets (that is, a dichotomy); the special case of discretization in which n = 2.
dichotomizeTo separate into two parts, to classify into two classes, or to categorize into two categories.
dichromacyThe quality of having two independent channels for conveying color information in the eye.
dichromatOne whose vision exhibits dichromacy; one who can distinguish only two primary colors.
dichromateAny salt of dichromic acid; in solution the orange dichromate anion.(Cr₂O₇²⁻) is in equilibrium with the yellow chromate anion (CrO₄²⁻), the relative amount of each ion depending on the pH; they are both very powerful oxidizing agents
dichromicfurnishing or giving two colours; said of defective vision, in which all the compound colours are resolvable into two elements instead of three
