Description
3,5-Dinitrosalicylic acid is an analytical-grade aromatic nitro compound supplied at minimum 99 % purity for p.a. laboratory use. It carries CAS number 609-99-4, EG number 210-204-3, and empirical formula C₇H₄N₂O₇, with a molar mass of 228,12 g/mol and a density of 1,709 g/cm³. The reagent is widely applied in colorimetric carbohydrate assays, reducing-sugar determination, and related biochemical or food-analytical methods that rely on a nitro-substituted salicylic acid chromogen. provides a practical quantity for method set-up, calibration series, and routine testing without large inventory. Available from manufacturer Carl ROTH, this p.a. material suits quality-control, teaching, and research laboratories that require a clearly specified 3,5-dinitrosalicylic acid grade. Its defined identity and physical data support reproducible preparation of assay reagents and consistent photometric response in established DNS protocols and related analytical workflows.

Questions about 3,5-Dinitrosalicylic acid, min. 99 %, p.a., 10 g, glass
What is this article?
3,5-Dinitrosalicylic acid, min. 99 %, p.a., 10 g, glass 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.
