Description
L-(+)-Ascorbic acid sodium salt is a biochemistry-grade reagent supplied at min. 99 % purity and aligned with USP quality expectations for laboratory vitamin work. Identified by CAS number 134-03-2 and EG nr. 205-126-1, it has the empirical formula C₆H₇O₆Na, a molar mass of 198,11 g/mol and a density of 1,88 g/cm³. supports preparation of aqueous stocks, antioxidant systems, buffers and reference solutions in biochemical and pharmaceutical research. Sodium ascorbate is widely used where a water-soluble form of ascorbic acid is preferred for redox studies, method development and related experimental setups. This material is offered by manufacturer Carl ROTH for biochemistry applications within the pharmacopoeia-quality vitamins portfolio. The defined composition and solid form facilitate accurate weighing and reproducible solution make-up. Intended for professional laboratory use, it suits research groups that require a clearly specified L-(+)-ascorbic acid sodium salt for routine and specialised biochemical workflows.

Questions about L-(+)-Ascorbic acid sodium salt, min. 99 %, USP, for biochemistry, 100 g
What is this article?
L-(+)-Ascorbic acid sodium salt, min. 99 %, USP, for biochemistry, 100 g 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?
