A chemical compound which appears under the form of a white, crystalline powder, is slightly hygroscopic, very soluble in water, forms sodium acid pyrophosphate at 225-250°C and sodium metaphosphate at 350-400°C, is derived by treating disodium phosphate with phosphoric acid, and is used in boiler-water treatment, electroplating, dyeing, acid cleansers, baking powders, cattle feed supplements, as a buffer, an emulsifier, a nutrient supplement in food, a lab reagent and an acidulant.

OBS

sodium dihydrogenphosphate: 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

MSP: This might be an in-house or a non-recognized abbreviation; not to be used alone, to avoid any risk of confusion.

OBS

Also known under the following commercial designation: Monosorb XP-4.

CAS number
DEF

Sel sodique de l'acide phosphorique se présentant sous forme de poudre, de cristaux ou de granules blancs, très solubles dans l'eau.

OBS

dihydrogénophosphate de sodium : 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

L'adjectif basique est correctement utilisé en français pour désigner un sel basique qui peut formellement libérer un anion OH-. Il est fortement déconseillé de l'utiliser en français dans le cas d'un sel acide contenant un ou plusieurs cations H+; on doit donc éviter les noms tels que «phosphate sodique monobasique» et «phosphate monobasique de sodium» qui sont des anglicismes de mauvais aloi.

OBS

[Utilisation :] Poudre levante, gélifiant, émulsifiant et stabilisant.

OBS

Aussi connu sous le nom commercial de Monosorb XP-4.
