Description
Sodium ammonium hydrogen phosphate tetrahydrate is a p.a. analytical reagent with a minimum assay of 98,5 %. It is identified by CAS number 7783-13-3 and EG number 235-860-8, with the empirical formula NaNH₄HPO₄ · 4 H₂O, a molar mass of 209,07 g/mol and a density of 0,85 g/cm³. This mixed phosphate salt is suited to qualitative cation detection and other analytical chemistry tasks that require a defined tetrahydrate composition. Laboratories use sodium ammonium hydrogen phosphate tetrahydrate in inorganic analysis and detection workflows that benefit from a reliable p.a. grade material. The combination of stated molar mass, density and hydrate form aids accurate weighing and solution make-up for routine qualitative work and related analytical applications in research and quality-control settings.

Questions about Sodium ammonium hydrogen phosphate, tetrahydrate, min. 98,5 %, p.a., 500 g
What is this article?
Sodium ammonium hydrogen phosphate, tetrahydrate, min. 98,5 %, p.a., 500 g is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Reference substances & reagents (other), inside Analytical standards & reference materials, in Lab chemicals.
A reference substance has a stated identity and a stated content, used to check a method or to standardise a titration. It is a more tightly specified article than a reagent grade bottle of the same name. The lot's certificate is part of the product.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
