Description
L(+)-Ascorbic acid is an analytical-grade reagent with a minimum purity of 99 % (p.a.), identified by CAS number 50-81-7 and the empirical formula C₆H₈O₆. It has a molar mass of 176,12 g/mol and a density of 1,65 g/cm³. Physical and identity data support its deployment in quantitative analysis, sample preparation, and related analytical workflows. The product is available from manufacturer Carl ROTH and carries EG number 200-066-2. Within reagent portfolios it sits among materials used for environmental analysis and as an acid-related reagent for analysis. The combination of stated assay, molar mass, and density provides clear documentation points for method validation and routine laboratory records. This pack size suits benches that need a manageable quantity of L(+)-ascorbic acid without excess bulk, while the plastic packaging supports straightforward storage and handling in the laboratory environment.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about L(+)-Ascorbic acid, min. 99 %, p.a., 100 g, plastic
What is this article?
L(+)-Ascorbic acid, min. 99 %, p.a., 100 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.
