Beschrijving
Potassium nonafluoro-1-butanesulfonate is a short-chain PFAS sulfonate salt supplied in the ROTI®Star line as an analytical reference for chromatography and related applications. It is registered under CAS number 29420-49-3 with empirical formula C₄F₉KO₃S and a molar mass of 338,2 g/mol. As the potassium salt of nonafluoro-1-butanesulfonic acid, it is relevant to laboratories that calibrate or verify methods for perfluorobutane sulfonates in environmental, industrial or residue matrices. The product is packed as 100 mg in glass, giving a practical working quantity for stock preparation, intermediate dilutions and multi-point calibration sets. This standard from manufacturer Carl ROTH fits into broader suites of PFAS chromatography standards used for identification and quantitative control. Defined composition and salt form support consistent handling in LC workflows, while the glass primary pack helps maintain sample integrity during storage and aliquoting. It is suited to research and routine analytical settings that require characterised fluorinated sulfonate references within regulated or exploratory PFAS programmes.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about Potassium nonafluoro-1-butanesulfonate, ROTI®Star, 100 mg, glass
What is this article?
Potassium nonafluoro-1-butanesulfonate, ROTI®Star, 100 mg, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in ICP, AAS & ion standards, inside Analytical standards & reference materials, in Chemicaliën.
An ICP, AAS or ion standard is a solution of a stated element or ion at a stated concentration, with an uncertainty. It is the calibration point of a spectrometer or an electrode. The matrix, often dilute acid, has to match the method. A standard past its expiry is not that concentration.
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?

Shelves beside this one are Chromatography standards (GC, HPLC, pesticides), Reference substances & reagents (other), 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.
