Description
3,4-Dihydroxybenzoic acid is an aromatic dihydroxybenzoic acid reagent supplied at a minimum purity of 97 % for chemical synthesis and laboratory research. It is defined by CAS number 99-50-3, EG number 202-760-0, empirical formula C₇H₆O₄ and a molar mass of 154,12 g/mol, providing a clear identity for documentation and method development. The material is packed as 10 g in glass, suitable for weighing and dissolution in organic or aqueous media according to the chosen protocol. Typical use areas include organic intermediate chemistry, analytical reference work and broader fine-chemical applications where a defined phenolic acid building block is required. This grade is available from manufacturer Carl ROTH for laboratories that need a compact glass pack of 3,4-dihydroxybenzoic acid with stated minimum assay. Physical handling follows standard solid-organic practice; users should consult the accompanying safety documentation before use. The combination of stated purity, molecular data and convenient 10 g pack size supports reproducible preparation of stock solutions and reaction mixtures in research and quality-control settings.

Questions about 3,4-Dihydroxybenzoic acid, min. 97 %, 10 g, glass
What is this article?
3,4-Dihydroxybenzoic acid, min. 97 %, 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.
Which category should I open next?
