Description
Choline dihydrogenphosphate is an organic phosphate salt with a minimum purity of 97 %, CAS number 83846-92-8 and empirical formula C₅H₁₆NO₅P. Its molar mass is 201,06 g/mol, supporting accurate stoichiometric work in synthesis and formulation. As a choline-based salt it is relevant to biochemical research, ionic-liquid studies and green-chemistry programmes that favour biocompatible cations and phosphate counter-ions. This grade from manufacturer Carl ROTH fits solvent and media development where a defined choline phosphate source is required. The clear assay and molecular identity help laboratories document reagent quality for exploratory synthesis, buffer-related work and comparative studies of choline derivatives. The compact pack size keeps handling straightforward on the bench while limiting excess inventory for specialised applications in sustainable laboratory chemistry.
This article belongs on Technical & synthesis grade solvents, in Solvents.

Questions about Choline-dihydrogenphosphate, min. 97 %, 25 g, plastic
What is this article?
Choline-dihydrogenphosphate, min. 97 %, 25 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Technical & synthesis grade solvents, inside Solvents, in Lab chemicals.
Technical and synthesis grades are for cleaning, for a coarse extraction and for chemistry that does not end in a chromatogram. They cost less because more impurity is allowed. They are the wrong bottle to make a mobile phase or a volumetric standard.
A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
Which category should I open next?
The category is Solvents. The sub-category is Technical & synthesis grade solvents. The catalogue is Lab chemicals.
Shelves beside this one are Analytical grade solvents (p.a.), HPLC & LC-MS grade solvents, Dry & deuterated solvents (NMR, synthesis) and Green & alternative solvents.
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.
