| naphthalene | <chemistry> A white crystalline aromatic hydrocarbon, C10H8, analogous to benzene, and obtained by the distillation of certain bituminous materials, such as the heavy oil of coal tar. It is the type and basis of a large number of derivatives among organic compounds. Formerly called also naphthaline. <chemistry> Naphthalene red, a yellow dyestuff obtained from certain nitro derivatives of naphthol. Source: Websters Dictionary (01 Mar 1998) |

| naphthalene acetic acid | <chemical> A synthetic auxin, often used in plant physiology and in plant tissue culture media because it is more stable than IAA. (18 Nov 1997) |
| naphthalene dioxygenase | <enzyme> Forms cis-(1r,2s)-dihydroxy-1,2-dihydronaphthalene; requires NADH Registry number: EC 1.14.12.- (26 Jun 1999) |
| naphthaleneacetic acids | Naphthalene derivatives containing the -ch2cco2h radical at the 1-position, the 2-position, or both. Compounds are used as plant growth regulators to delay sprouting, exert weed control, thin fruit, etc. (12 Dec 1998) |
| naphthalenes | Two-ring crystalline hydrocarbons isolated from coal tar. They are used as intermediates in chemical synthesis, as insect repellents, fungicides, lubricants, preservatives, and, formerly, as topical antiseptics. (12 Dec 1998) |
