Description
Perfluoro-n-hexanesulfonic acid is a C₆ perfluorinated sulfonic acid standard with CAS number 355-46-4 and empirical formula C₆HF₁₃O₃S. It has a molar mass of 400,11 g/mol and a boiling point of 238,5 °C, providing clear physicochemical anchors for method development and compound verification. Packaged as 50 mg in a glass ampoule, the material is well suited to the preparation of calibration stocks and quality-control solutions for chromatographic PFAS analysis. Analytical laboratories use this chain length in multi-residue panels for environmental, industrial and regulatory testing where hexanesulfonic acid must be distinguished from shorter and longer homologues. The product comes from manufacturer Carl ROTH and is identified under EG number 206-587-1. Glass ampoule supply supports accurate dispensing of small masses and helps protect the neat acid until it is reconstituted for LC–MS, GC or complementary analytical workflows.
This article is part of HPLC & LC-MS grade solvents, in Solvents. See also Analytical grade solvents (p.a.).

Questions about Perfluoro-n-hexanesulfonic acid, 50 mg, glass ampoule
What is this article?
Perfluoro-n-hexanesulfonic acid, 50 mg, glass ampoule is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in HPLC & LC-MS grade solvents, inside Solvents, in Produits chimiques.
HPLC grade limits the absorbance and the residue that would appear as peaks or baseline drift. LC-MS grade goes further on metal ions and on particles that would suppress a mass spectrum. A solvent that is only analytical grade is a false economy on an LC-MS system.
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 HPLC & LC-MS grade solvents. The catalogue is Produits chimiques.
Shelves beside this one are Analytical grade solvents (p.a.), 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.
