  • Crop Protection
  • Photography
Universal entry(ies)
CH4O2
formula, see observation
H2C(OH)2
formula, see observation
463-57-0
CAS number
DEF

A chemical compound [which] is the simplest geminal diol, and formally the second simplest carbohydrate (after formaldehyde).

CONT

The chemical equilibrium between formaldehyde (HCHO) and its hydrated form, methanediol (CH2(OH)2), is computationally investigated in solvent water.

CONT

Formaldehyde solution [is] a solution of about 37% by weight of formaldehyde gas in water, usually with 10-15% methanol added to prevent polymerization.

OBS

methanediol: form recommended by the International Union of Pure and Applied Chemistry (IUPAC) for the systematic name corresponding to the CAS number indicated on the present record.

OBS

Methanediol is a product of the hydration of formaldehyde H2C=O, and predominates in water solution: the equilibrium constant being about 10³, and a 5% by weight solution of formaldehyde in water is 80% methanediol.

OBS

Also known under a large number of commercial names, among which: BFV; FA; Fannoform; Formalin; Formalith; Formol; Fyde; Hoch; Ivalon; Karsan; Lysoform; Morbicid; Paraform; Superlysoform.

OBS

formaldehyde: also refers to formaldehyde in the gaseous form (methanal).

OBS

Chemical formulas: CH4O2 or H2C(OH)2

CAS number
OBS

Le formaldéhyde est le plus simple des aldéhydes. [...] On l’utilise souvent sous forme de solution aqueuse renfermant 37 % de formaldéhyde (en poids) et 10 à 15 % de méthanol pour empêcher la polymérisation.

OBS

méthanediol : forme recommandée par l’Union internationale de chimie pure et appliquée (UICPA) pour le nom systématique correspondant au numéro CAS indiqué sur la présente fiche.

OBS

Aussi connu sous les désignations commerciales suivantes :Formaline; Formol; Morbicid.

OBS

Formol : Solution commerciale du méthanal(35 à 40 %) mélangée de méthanol(10 à 15 %). La solution officinale doit contenir 35 % de méthanal. Formaline : Soluté officinal de méthanal.

OBS

Le formaldéhyde [...] peut être employé à l’état gazeux pour la désinfection des habitations et à l’état dissous comme germicide et insecticide [méthanal].

OBS

Formules chimiques : CH4O2 ou H2C(OH)2

Record 2 2014-03-21

English

Subject field(s)
  • Immunology
DEF

[A vaccine made of] prepared inactivated [virus] particles disrupted with detergents.

OBS

[Split] vaccines have been shown to induce fewer side effects in the vaccinees [than whole virus vaccines] and are just as immunogenic.

Key term(s)
  • split virus vaccine

French

Domaine(s)
  • Immunologie
DEF

[Vaccin composé] de particules [virales] obtenues après [le] traitement [de virions entiers inactivés] par [des] détergents.

CONT

Jusqu'en automne 2000, il existait 3 types de vaccins influenza : un vaccin à virus fragmenté(type Fluarix), un vaccin à sous-unités(type Influvac) [et] un vaccin à virus entier inactivé par la formaline [...]

Key term(s)
  • vaccin à virions fragmentés
  • vaccin à virus fragmentés

Spanish

Campo(s) temático(s)
  • Inmunología
DEF

Vacuna [...] hecha a partir del fraccionamiento del virus con un agente separador [por ejemplo, un detergente], posee antígenos tanto internos como externos que estimulan ampliamente la producción de anticuerpos y están libres de lípidos reactogénicos, por lo que son muy bien toleradas.
