Description
Gallic acid monohydrate is a trihydroxybenzoic acid hydrate supplied at a minimum purity of 99 % for analytical chemistry, chromatography standards and phytochemical work. It carries CAS number 5995-86-8 and EG number 205-749-9, with the empirical formula C₇H₆O₅ · H₂O and a molar mass of 188,14 g/mol. The flash point is 250 °C. As a well-characterised phenolic acid monohydrate, it serves as a reference and reagent in antioxidant studies, natural-product analysis and chromatographic calibration. This material is High assay and clear identity data support reproducible results in quality-control and research environments that rely on defined gallic acid monohydrate. The packaging format suits repeated weighing and stock preparation while aligning with common phytochemical and chromatographic workflows.

Questions about Gallic acid monohydrate, min. 99 %, 50 g, plastic
What is this article?
Gallic acid monohydrate, min. 99 %, 50 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Reference substances & reagents (other), inside Analytical standards & reference materials, in Lab chemicals.
A reference substance has a stated identity and a stated content, used to check a method or to standardise a titration. It is a more tightly specified article than a reagent grade bottle of the same name. The lot's certificate is part of the product.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
