Beschreibung
Eriochroomblauwzwart R (C.I. 15705) is een metaalindicator bedoeld voor complexometrische analyse in analytische laboratoria. De kleurstof wordt gekenmerkt door CAS-nummer 2538-85-4, EG-nummer 219-810-2, de empirische formule C₂₀H₁₃N₂O₅SNa en een molaire massa van 416,39 g/mol, wat een nauwkeurige documentatie in standaardwerkprocedures en reagenslogboeken mogelijk maakt. De classificatie binnen de analytische chemicaliën, indicatoren en metaalindicatoren onderstreept de rol ervan in klassieke volumetrische methoden. Het product is verkrijgbaar bij fabrikant Carl ROTH en ondersteunt routinematige complexometrie waarbij een azokleurstof als natriumzout met deze Colour Index-aanduiding is gespecificeerd. De glazen verpakking helpt de vaste stof tussen openingen te beschermen en vergemakkelijkt het nauwkeurig afwegen van kleine laboratoriumporties. Analisten die hardheidstests voor water, bepalingen van metaalionen of aanverwante complexometrische assays uitvoeren, kunnen deze indicator opnemen in vastgestelde titratieschema's met een consistent kleurveranderingsgedrag bij het eindpunt.
Dit artikel hoort bij Referentiestoffen & reagentia (overig), in Analytische standaarden & referentiematerialen.

Questions about Eriochroomblauwzwart R (C.I. 15705), voor complexometrie, 5 g, glas
What is this article?
Eriochroomblauwzwart R (C.I. 15705), voor complexometrie, 5 g, glas 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 Labor- und Industriechemikalien.
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?
The category is Analytical standards & reference materials. The sub-category is Reference substances & reagents (other). The catalogue is Labor- und Industriechemikalien.
Shelves beside this one are ICP, AAS & ion standards, Chromatography standards (GC, HPLC, pesticides), Volumetric standard solutions (titration), Reagents for analysis (Ph. Eur., ASTM, DIN), Spectroscopy & physical property standards and Indicators & indicator solutions.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
