| vanadium compounds | Inorganic compounds that contain vanadium as an integral part of the molecule. (12 Dec 1998) |
|---|---|
| magnesium compounds | Inorganic compounds that contain magnesium as an integral part of the molecule. (12 Dec 1998) |
| manganese compounds | Inorganic chemicals that contain manganese as an integral part of the molecule. (12 Dec 1998) |
| volatile organic compounds | (VOC) Emissions of non-methane hydrocarbons, measured by standard DEQ methods. (05 Dec 1998) |
| gold compounds | Inorganic compounds that contain gold as an integral part of the molecule. (12 Dec 1998) |
| cetrimonium compounds | Cetyltrimethylammonium compounds that have cationic detergent, antiseptic, and disinfectant activities. They are used in pharmaceuticals, foods, and cosmetics as preservatives; on skin, mucous membranes, etc., as antiseptics or cleansers, and also as emulsifiers. These compounds are toxic when used orally due to neuromuscular blockade. (12 Dec 1998) |
| mercury compounds | Inorganic compounds that contain mercury as an integral part of the molecule. (12 Dec 1998) |
| meso compounds | Compounds containing more than one asymmetric carbon atom, with configurations about them so balanced that the molecule as a whole possesses a plane of symmetry, although the individual carbon atoms do not; such compounds are not optically active; e.g., ribitol, mucic acid, meso-inositol, meso-cystine. (05 Mar 2000) |
| chlorine compounds | Inorganic compounds that contain chlorine as an integral part of the molecule. (12 Dec 1998) |
| methacholine compounds | A group of compounds that are derivatives of beta-methylacetylcholine (methacholine). (12 Dec 1998) |
| methonium compounds | Compounds containing polymethylene bis-trimethylammonium cations. Members of this group frequently act as ganglionic blockers and neuromuscular depolarising agents. (12 Dec 1998) |
| methylmercury compounds | Organic compounds in which mercury is attached to a methyl group. (12 Dec 1998) |
| methylurea compounds | Urea compounds which are substituted with one or more methyl groups. (12 Dec 1998) |
| chromium compounds | Inorganic compounds that contain chromium as an integral part of the molecule. (12 Dec 1998) |
| chromogenic compounds | Colourless, endogenous or exogenous pigment precursors that may be transformed by biological mechanisms into coloured compounds; used in biochemical assays and in diagnosis as indicators, especially in the form of enzyme substrates. Synonym: chromogens (not to be confused with pigment-synthesizing bacteria also called chromogens). (12 Dec 1998) |
