Description
Gallic acid is an anhydrous analytical reagent offered at a minimum purity of 98 % in p.a. and ACS quality. Identified by CAS number 149-91-7 and empirical formula C₇H₆O₅, it has a molar mass of 170,12 g/mol, a density of 1,69 g/cm³ and a flash point of 250 °C, giving laboratories clear physical data for handling, documentation and method setup. The anhydrous grade supports workflows where water content must remain tightly controlled, while p.a. and ACS designation aligns with common expectations for reagent identity and consistency. Glass packaging aids orderly storage and dispensing at the bench. With EG number 205-749-9 for substance identification, this gallic acid pack is suited to routine and demanding laboratory applications that rely on a defined, anhydrous C₇H₆O₅ reagent of at least 98 % purity.

Questions about Gallic acid, min. 98 %, p.a., ACS, anhydrous, 100 g, glass
What is this article?
Gallic acid, min. 98 %, p.a., ACS, anhydrous, 100 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.
