Description
L(+)-Ascorbic acid is a pharmacopoeia-grade vitamin C reagent with a minimum purity of 99 % conforming to Ph. Eur., USP and BP requirements. It is identified by CAS number 50-81-7 and the empirical formula C₆H₈O₆, with a molar mass of 176,12 g/mol and a density of 1,65 g/cm³. This offers a practical quantity for analytical chemistry, pharmaceutical development and biochemical laboratory work. L(+)-Ascorbic acid is widely used as an antioxidant, reducing agent and reference material in titrations, chromatographic assays and quality-control procedures. The grade from manufacturer Carl ROTH supports environments that require documented compliance with major pharmacopoeias. Defined purity and physical data help laboratories achieve reproducible results in method development, stability studies and routine vitamin analysis. Whether preparing standards, performing redox determinations or supporting formulation work, users obtain a consistent solid reagent suited to regulated and research settings that specify L(+)-ascorbic acid of Ph. Eur., USP and BP quality.

Questions about L(+)-Ascorbic acid, min. 99 %, Ph. Eur., USP, BP, 100 g, plastic
What is this article?
L(+)-Ascorbic acid, min. 99 %, Ph. Eur., USP, BP, 100 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Acids, inside Acids & bases, in Lab chemicals.
An acid on this shelf is the substance itself, concentrated or as a stated solution: hydrochloric, sulfuric, nitric, acetic and the rest. Concentration, purity and the trace metals decide the use. A concentrated acid and a volumetric solution of the same name are different products, and both burn.
An acid donates a proton. A base accepts one. In the bottle, the practical differences are the concentration, the purity and the anion or cation that comes along. Concentrated mineral acids are a different article from a dilute volumetric solution. The water in the acid, and the trace metals, decide whether it can be used for analysis. Check the substance on PubChem and the classification on ECHA CLP. Transport is the UNECE dangerous-goods framework. The legal texts are the CLP Regulation and REACH.
Which category should I open next?
