Description
Diphenylamine-4-sulfonic acid sodium salt is an analytical-grade redox indicator supplied at p.a., ACS quality for demanding laboratory work. With CAS number 6152-67-6, empirical formula C₁₂H₁₀NNaO₃S and a molar mass of 271,27 g/mol, it provides a well-defined chemical identity for reproducible titration and redox applications. The material is Categories such as redox indicators and analytical chemicals highlight its role in endpoint detection and related wet-chemical methods. Prepared to p.a., ACS specifications from manufacturer Carl ROTH, the salt supports routine quality control, method development and teaching laboratories that require consistent indicator performance. Its sodium salt form aids handling in aqueous systems commonly used for redox titrations. EG number 228-165-6 further identifies the substance for regulatory and documentation workflows. This compact glass unit is practical for laboratories that need reliable indicator stock without excess inventory.

Questions about Diphenylamine-4-sulfonic acid sodi. salt, p.a., ACS, 10 g, glass
What is this article?
Diphenylamine-4-sulfonic acid sodi. salt, p.a., ACS, 10 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.
