Description
Citric acid monohydrate is an analytical-grade organic acid supplied at min. 99,5 % p.a., ACS and ISO quality for laboratory reagents and reference use. The empirical formula is C₆H₈O₇·H₂O, molar mass 210,14 g/mol and density 1,54 g/cm³; the boiling point is reported above 170 °C. CAS number 5949-29-1 and EG nr. 611-842-9 apply. This monohydrate form is widely employed in buffer systems, pH adjustment, complexometric work and environmental or food-related analytical preparations where a defined citric acid source is required. from manufacturer Carl ROTH provides a convenient stock quantity for routine method development and sample preparation. Crystalline handling is straightforward under standard laboratory conditions. Specify this p.a./ACS/ISO grade when protocols call for high-purity citric acid monohydrate rather than anhydrous material, and consult the safety data sheet for correct storage and personal protection during weighing and dissolution.
This article belongs on Analytical grade solvents (p.a.), in Solvents.

Questions about Citric acid monohydrate, min. 99,5 % p.a., ACS, ISO, 500 g, plastic
What is this article?
Citric acid monohydrate, min. 99,5 % p.a., ACS, ISO, 500 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Analytical grade solvents (p.a.), inside Solvents, in Lab chemicals.
An analytical-grade solvent, often marked p.a., has impurity limits tight enough for classical analysis and for preparing reagents. It is not automatically low enough in UV absorbance for HPLC, and it is not dry enough for a water-sensitive reaction. The grade is the purchase.
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 Analytical grade solvents (p.a.). The catalogue is Lab chemicals.
Shelves beside this one are HPLC & LC-MS grade solvents, Dry & deuterated solvents (NMR, synthesis), Technical & synthesis grade solvents and Green & alternative solvents.
What should I check before I order?
