Description
Ninhydrin is a high-purity analytical reagent supplied at min. 99 %, p.a., ACS grade, with CAS number 485-47-2 and empirical formula C₉H₆O₄. Its molar mass is 178,15 g/mol, supporting precise stoichiometric work in qualitative and quantitative laboratory protocols. This material is widely recognised as a classical staining reagent and is suited to applications in environmental analysis as well as general reagent and reference-material workflows where clear, reproducible colour development is required. The product is Physical and identity data align with the stated ACS and p.a. specifications, giving analysts a reliable basis for documentation and method transfer. Sourced from manufacturer Carl ROTH, this ninhydrin grade integrates readily into established staining and detection procedures without unnecessary reformulation. Use it where controlled purity, defined molecular composition, and stable packaging matter for consistent analytical performance across environmental and life-science laboratories.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about Ninhydrin, min. 99 %, p.a., ACS, 25 g, glass
What is this article?
Ninhydrin, min. 99 %, p.a., ACS, 25 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.
