DEF

A chemical compound which appears under the form of colorless needles becoming red in air, is derived by the reduction of m-dinitrobenzene or nitroaniline with iron and hydrochloric acid followed by a purification by crystallization, and is used in the manufacture of dyestuffs, the detection of nitrite, in ion-exchange resins, block polymers, corrosion inhibitors, photography, as a laboratory reagent, a textile developing agent and a vulcanizing agent.

OBS

Also known under a large number of commercial designations, among which: AAPCO 2330; C.I. 76025; Developer 11; Developer C; Developer H; Developer M; Direct Brown BR; Direct Brown GG; UN 1673.

OBS

m-phenylenediamine: part of the Ingredient Disclosure List of the Hazardous Products Act (Registration SOR/88-64, December 31, 1987).

OBS

The prefixes "ortho-", "meta-" and "para-", along with their corresponding abbreviations ("o-", "m-" and "p-"), appear in italics and are ignored in alphabetizing. According to the actual chemical nomenclature rules in organic chemistry (in 2003), the numbers designating the positions of the disubstitution groups (1,2- for "ortho-", 1,3- for "meta-" and 1,4- for "para-") are to be preferred to the symbols "o-", "m-" and "p-". Furthermore, the prefixes "ortho-", "meta-" and "para-" should not be used anymore, and their corresponding abbreviations ("o-", "m-", and "p-") will soon be judged to be avoided, if not totally condemned.

OBS

MPDA: This might be an in-house or a non-recognized abbreviation; not to be used alone, to avoid any risk of confusion.

Les préfixes de position «ortho-», «méta-» et «para-», tout comme les abréviations correspondantes «o-», «m-» et «p-», s'écrivent en italique et n'interviennent pas dans une classification par ordre alphabétique. Selon les règles de nomenclature de chimie organique en vigueur aujourd'hui (en 2003), il est recommandé d'utiliser les chiffres 1,2-, 1,3- et 1,4-, respectivement. Les préfixes «ortho-», «méta-» et «para-» ne doivent plus être utilisés. L'usage des symboles correspondants («o-», «m-» et «p-») sera bientôt fortement déconseillé, sans être exclu.

DEF

The most widely used and effective of the aniline derivative dyes, producing colours ranging from the lightest brown to jet black. Its very action depends on oxidation, usually effected by hydrogen peroxide and this reaction results in the formation of an intermediate product known as Bandrowsky's Base. ... This type of dye is variously known as an amino dye, aniline derivative dye, instantaneous dye, oxidation dye, peroxide dye, synthetic organic dye, two bottle dye.
