Description
Tartrazine is offered as ROTICHROM® Pestilyse® HPLC reference material for chromatographic and environmental analytical applications. It is identified by CAS number 1934-21-0 and EG nr. 217-699-5, with the empirical formula C₁₆H₉N₄Na₃O₉S₂ and a molar mass of 534,36 g/mol. These core identity parameters support accurate labelling, method transfer, and cross-checking against pharmacopoeial or in-house reference lists when the dye is used as an analytical standard. The pack contains 250 mg in glass, a practical quantity for preparing stock and working solutions used in HPLC calibration, system suitability, and qualitative confirmation. Laboratories active in environmental analysis, colourant monitoring, and broader chromatography programmes can rely on the defined CAS and formula data when building multi-analyte sequences or single-component assays. Supplied within the ROTICHROM® Pestilyse® HPLC range from manufacturer Carl ROTH, tartrazine is presented for routine research and quality-control settings where traceable chemical identity matters. Clear molar mass and regulatory numbers simplify LIMS registration, safety documentation, and consistent use across validated analytical workflows.
This article is part of Chromatography standards (GC, HPLC, pesticides), in Analytical standards & reference materials.

Questions about Tartrazine, ROTICHROM® Pestilyse® HPLC, 250 mg, glass
What is this article?
Tartrazine, ROTICHROM® Pestilyse® HPLC, 250 mg, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Chromatography standards (GC, HPLC, pesticides), inside Analytical standards & reference materials, in Lab chemicals.
A chromatography standard is the substance, or the mix, injected so a peak can be named and quantified. Pesticide mixes, residual-solvent mixes and single-compound standards are different articles. The concentration and the solvent are the specification. The solvent has to be one the method may contain.
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.
