Description
Sodium dihydrogen phosphate min. 99 % is an HPLC-grade salt supplied for liquid chromatography and related analytical applications. The material carries CAS number 7558-80-7, EG number 231-449-2 and the empirical formula NaH₂PO₄, with a molar mass of 119,98 g/mol and a density of 2,357 g/cm³. High minimum purity supports buffer preparation, mobile-phase work and other HPLC workflows where consistent salt quality is required. provides a convenient laboratory quantity for method development, routine separations and quality-control use. Offered by manufacturer Carl ROTH, this sodium dihydrogen phosphate fits chromatography suites focused on LC, HPLC and LC-MS applications. Analysts can rely on the stated composition and physical data when preparing aqueous buffers or adjusting ionic strength in reversed-phase and ion-exchange methods. Clear documentation of CAS, EG number and molar mass simplifies inventory control and method transfer. This HPLC-oriented phosphate salt combines defined purity with practical packaging for everyday chromatographic practice.

Questions about Sodium dihydrogen phosphate, min. 99 %, HPLC, 50 g, glass
What is this article?
Sodium dihydrogen phosphate, min. 99 %, HPLC, 50 g, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in HPLC accessories, inside HPLC columns & accessories, in Chromatography equipment.
HPLC accessories are the unions, the ferrules, the lamp and the mixer parts around the pump and the detector. A ferrule that has been swaged on one fitting does not reseal on another. The part has to be the one for that thread and that tubing.
An HPLC column is a tube packed, or coated, with a stationary phase. The sample is carried through it by a liquid, and the compounds leave at different times. The phase, the particle size, the length and the internal diameter decide the separation. A guard column is a short sacrificial piece in front of the analytical column. Fittings and tubing have a bore that either preserves the peak or smears it. Compound names follow IUPAC. Data are on PubChem. Method grades often cite the European Pharmacopoeia or USP.
Which category should I open next?
The category is HPLC columns & accessories. The sub-category is HPLC accessories. The catalogue is Chromatography equipment.
Shelves beside this one are HPLC columns, HPLC fittings, tubing & inline filters and HPLC guard columns.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
