English

Subject field(s)
  • Chemical Elements and Compounds
Universal entry(ies)
C7H8O
formula, see observation
CH3C6H4OH
formula, see observation
108-39-4
CAS number
OBS

Properties: Colorless to yellowish liquid ; phenol-like odor. ... Derivation: By fractional distillation of crude cresol (from coal tar); also synthetically.

OBS

Use: in disinfectants and fumigants; in photographic developers, explosives.

OBS

3-methylphenol: form recommended by the IUPAC (International Union of Pure and Applied Chemistry) for the systematic name.

OBS

m-cresol: the prefix "m-" must be italicized; 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

Also known under the following commercial designations: RCRA waste number U052; UN 2076.

OBS

Chemical formula: C7H8O or CH3C6H4OH

OBS

Liquide incolore ou jaunâtre, odeur phénolique [...] Utilisation : désinfectant, fumigation, développement photographique, explosifs.

OBS

3-méthylphénol : forme recommandée par l'UICPA (Union internationale de chimie pure et appliquée) pour le nom systématique.

OBS

m-crésol : Le préfixe «m-» s'écrit en italique; 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 : C7H8O ou CH3C6H4OH
