methoxy-comb. form

Stress is usually determined by a subsequent element and vowels may be reduced accordingly.

Origin: Formed within English, by compounding. Etymons: meth- comb. form, oxy- comb. form².

Etymology: < meth- comb. form + oxy- comb. form², after methoxyl n. and hydroxy- comb. form.Formations are found from the last quarter of the 19th cent.

1939 Proc. Royal Soc. B. 127 163 A solution of m-methoxyacetophenone (50 g.) and anisaldehyde (45·4 g.) in alcohol (150 cc.) was shaken for a few minutes with aqueous sodium hydroxide.

1964 N. G. Clark Mod. Org. Chem. xxiii. 479 Like the aromatic aldehydes, the ketones are frequently employed as synthetic intermediates, and as ingredients in perfumery. Some simple derivatives possess quite delightful odours, for example, p-methylacetophenone (hawthorn), p-methoxyacetophenone (heliotrope).

1991 Lancet 2 Mar. 566/1 From a basic extract of a ‘tea’ prepared from the medicine as prescribed by the above practitioner we separated significant amounts..of a compound tentatively identified..as 2′-hydroxy-4′-methoxyacetophenone.

methoxychlor n.

Brit.

/mᵻˈθɒksɪklɔː/

U.S.

/məˈθɑksᵻˌklɔr/

an organochlorine insecticide of similar chemical structure to DDT, but with lower toxicity and persistence in the environment; 1,1,1-trichloro-2,2-bis(p-methoxyphenyl)ethane, (C₆H₄OCH₃)₂CHCCl₃.

ΚΠ

1948 Science 9 Jan. 38/3 After consultation.., ‘methoxychlor’ has been selected as the common name for 2,2-bis(p-methoxyphenyl)1,1,1-trichloroethane, the methoxy analog of DDT.

1959 H. Martin Sci. Princ. Crop Protection (ed. 4) x. 203 When methoxychlor was used instead [of DDT], Carter et al. were unable to detect the insecticide in the milk.

1973 Globe & Mail (Toronto) 8 Sept. 8/3 City golf courses and cemeteries were relatively mosquito-free, having been fogged all along with methoxychlor, a new insecticide that doesn't have the harmful properties of DDT.
