formula, see observation
DEF

A chemical compound which appears under the form of crystals, is soluble in water and alcohol and is used in organic synthesis.

OBS

3-nitrobenzene-1-sulfonic acid: form recommended by the IUPAC (International Union of Pure and Applied Chemistry).

OBS

m-nitrobenzenesulfonic acid: 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

Chemical formula: C6H5NO5S or C6H4NO2SO3H

DEF

Produit chimique se présentant sous la forme de cristaux, soluble dans l'eau et l'alcool, utilisé en synthèse organique.

OBS

acide 3-nitrobenzène-1-sulfonique : forme recommandée par l'UICPA (Union internationale de chimie pure et appliquée).

OBS

acide m-nitrobenzènesulfonique : fait partie de la Liste de divulgation des ingrédients de la Loi sur les produits dangereux (du Canada; enr. DORS s/88-64, 31 déc. 1987).

OBS

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.

OBS

Formule chimique : C6H5NO5S ou C6H4NO2SO3H
