Description
Zincon is an analytical-grade metal indicator offered at minimum 95 % purity, p.a., with empirical formula C₂₀H₁₅N₄NaO₆S and molar mass 462,41 g/mol (CAS 62625-22-3). EG number 263-651-1 supports clear identification in quality systems and chemical inventories. Categories such as analytical chemicals and metal indicators reflect its typical use for monitoring selected metal ions under controlled conditions. Product from manufacturer Carl ROTH arrives in a compact glass pack suited to precise dispensing on the analytical bench. Documented assay, formula and CAS data help laboratories maintain traceable reagent lists and method descriptions. The solid form is convenient for preparing indicator solutions according to established protocols. This grade is aimed at research and routine analytical environments that require a reliable p.a. zincon portion with transparent composition data and no unspecified performance claims.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about Zincon, min. 95 %, p.a., 1 g, glass
What is this article?
Zincon, min. 95 %, p.a., 1 g, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Analytical grade solvents (p.a.), inside Solvents, in Lab chemicals.
An analytical-grade solvent, often marked p.a., has impurity limits tight enough for classical analysis and for preparing reagents. It is not automatically low enough in UV absorbance for HPLC, and it is not dry enough for a water-sensitive reaction. The grade is the purchase.
A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
Which category should I open next?
The category is Solvents. The sub-category is Analytical grade solvents (p.a.). The catalogue is Lab chemicals.
Shelves beside this one are HPLC & LC-MS grade solvents, Dry & deuterated solvents (NMR, synthesis), Technical & synthesis grade solvents and Green & alternative solvents.
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.
