AROMATIC ODOUR [7 records]

C7H4F3NO2
formula, see observation
NO2C6H4CF2
formula, see observation
98-46-4
CAS number
DEF

A chemical compound which appears under the form of a pale straw, thin oily liquid with a distinct aromatic odour, is soluble in organic solvents and insoluble in water.

OBS

1-nitro-3-(trifluoromethyl)benzene: form recommended by the IUPAC (International Union of Pure and Applied Chemistry).

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: C7H4F3NO2 or NO2C6H4CF2

OBS

The word "alpha" must be replaced by the corresponding Greek letter or italicized.

1-nitro-3-(trifluorométhyl)benzène : forme recommandée par l'UICPA (Union internationale de chimie pure et appliquée).

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

Ke nit «alpha» doit être remplacé par la lettre grecque correspondante ou être écrit en italique.

English

Subject field(s)
  • Analytical Chemistry
  • Environmental Studies and Analyses
OBS

Since "aromatic" means "having a distinctive pleasing odor", the term "aromatic odour" appears questionable to us. It is not the odour that is "aromatic", but the product possessing the pleasing odour.

French

Domaine(s)
  • Chimie analytique
  • Études et analyses environnementales
OBS

(agréable et pénétrante); Cahier Enviroguide Cyclohexane, chap. 1.

OBS

"aromatique" : De la nature des aromates; qui exhale une odeur agréable, suave : [Ex. : ] Plante, huile aromatique.

OBS

On voit par la définition qui précède que l'expression "odeur aromatique" est douteuse : on ne peut dire, en effet, d'une odeur, qu'elle exhale une odeur (...). Il voudrait mieux parler d'un produit aromatique ou d'une odeur agréable, le premier produisant la seconde.
