Description
Tetraethylthionopyrophosphate (O,S-TEPP) is a ROTICHROM® Pestilyse® HPLC reference substance supplied in a 50 mg pack for specialised chromatographic analysis. Registered under CAS number 645-78-3, it has the empirical formula C₈H₂₀O₆P₂S and a molar mass of 306,25 g/mol. This HPLC-oriented grade supports environmental analysis and chromatography tasks, including calibration, peak verification and quantitative determination of organophosphorus-related analytes. The compact unit size is practical for preparing dilute working standards and for laboratories that require only small amounts of reference material per analytical series. O,S-TEPP from manufacturer Carl ROTH is positioned for use in residue and environmental workflows where a clearly specified HPLC standard improves method robustness. Apply it within validated laboratory procedures for gas or liquid chromatography to aid consistent identification and measurement in environmental and pesticide-analysis contexts.
This article is part of Chromatography standards (GC, HPLC, pesticides), in Analytical standards & reference materials.

Questions about Tetraethylthionopyrophosphate (O,S-TEPP), ROTICHROM® Pestilyse® HPLC, 50 mg
What is this article?
Tetraethylthionopyrophosphate (O,S-TEPP), ROTICHROM® Pestilyse® HPLC, 50 mg is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Chromatography standards (GC, HPLC, pesticides), inside Analytical standards & reference materials, in Lab chemicals.
A chromatography standard is the substance, or the mix, injected so a peak can be named and quantified. Pesticide mixes, residual-solvent mixes and single-compound standards are different articles. The concentration and the solvent are the specification. The solvent has to be one the method may contain.
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.
