Description
Glyoxal-bis-(2-hydroxyanil) is an analytical metal indicator with a minimum purity of 97 %, CAS number 1149-16-2 and empirical formula C₁₄H₁₂N₂O₂. Its molar mass is 240,36 g/mol, and it is identified under EG number 214-560-0. The defined composition supports preparation of indicator solutions and controlled response to selected cations under standard bench conditions. This grade from manufacturer Carl ROTH is suited to qualitative and quantitative workflows where a compact solid portion enables accurate weighing and dilution. The glass packaging helps protect the material during storage and routine handling. Glyoxal-bis-(2-hydroxyanil) fits catalogues of analytical chemicals used as metal indicators, offering a clearly specified organic ligand for titration setups, complex formation studies and teaching or research protocols that require a reliable indicator of known purity and molecular identity.
This article is part of Reference substances & reagents (other), in Analytical standards & reference materials.

Questions about Glyoxal-bis-(2-hydroxyanil), min. 97 %, 1 g, glass
What is this article?
Glyoxal-bis-(2-hydroxyanil), min. 97 %, 1 g, glass 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.
Which category should I open next?
