Description
Cacotheline is an analytical-grade metal indicator supplied at a minimum purity of 95 %, p.a., for laboratory use. Identified by CAS number 561-20-6 and EG number 209-215-6, it has the empirical formula C₂₁H₂₁N₃O₇·HNO₃·H₂O and a molar mass of 508,44 g/mol. This reagent belongs to the metal-indicator class of analytical chemicals and supports complexometric and related metal-ion detection workflows where a defined cacotheline grade is required. The material is Prepared to p.a. quality expectations, it fits routine and research applications that call for a documented indicator with clear identity data. Available from manufacturer Carl ROTH, the product combines a compact glass unit with fully specified chemical parameters, enabling straightforward integration into existing indicator inventories and method documentation without ambiguity on grade, formula, or pack presentation.

Questions about Cacotheline, min. 95 %, p.a., 1 g, glass
What is this article?
Cacotheline, min. 95 %, p.a., 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?
