CAS number
DEF

A compound containing the radical NO2-, salt or ester of nitrous acid, which is both an oxidizing and a reducing substance, is extremely reactive to organic matter, is labile to heat, and is used in the food industry where it is added to meat to produce the characteristic cured-meat colour and flavour, to eliminate the problem of warmed-over flavour in cured meats and to prevent the outgrowth of Clostridium botulinum.

CONT

Nitrogen dioxide (NO2) is chemiadsorbed by triethanolamine (TEA) as ion NO2-. Nitrite ion is analysed by means of visible spectrophotometry.

OBS

Also known, in the biological field, under the name of "smooth muscle inhibitory factor (SMIF)."

OBS

nitrite: form recommended by the IUPAC (International Union of Pure and Applied Chemistry) for the systematic name corresponding to the CAS number indicated on the present record; term adopted by Environment Canada, used in the list of pollutants measured in the National Air Pollution Surveillance Network (NAPS).

DEF

Sel ou ester de l'acide nitreux, qui renferme le radical NO2-.

CONT

[Les nitrites] sont tantôt réducteurs, tantôt oxydants. Les deux nitrites les plus importants sont celui de potassium, que l'on introduit [...] dans les viandes fumées, et celui de sodium qui, en chimie organique, sert à diazoter les amines et, par suite, à préparer des matières colorantes.

CONT

Pour doser les ions nitrate en solution aqueuse, on opère en trois étapes successives : · Réduction des ions nitrate en ions nitrite par l'hydroquinone. · Réaction de diazotation avec l'acide 4-aminobenzènesulfonique (acide sulfanilique). · Réaction de couplage en milieu faiblement acide avec la N-(1-naphtyl)éthylènediamine pour donner un colorant azoïque rouge violet.

OBS

nitrite : forme recommandée par l'UICPA (Union internationale de chimie pure et appliquée) pour le nom systématique correspondant au numéro CAS indiqué sur la présente fiche; terme retenu par Environnement Canada, utilisé dans la liste des polluants mesurés par le Réseau national de surveillance de la pollution atmosphérique (RNSPA).
