Description
Pyrimethamine is a defined analytical reference standard offered as ROTICHROM® Pestilyse® HPLC grade for demanding chromatographic work. Identified by CAS number 58-14-0 and the empirical formula C₁₂H₁₃ClN₄, it has a molar mass of 248,71 g/mol and a density of 1,217 g/cm³. The substance is packed as 100 mg in glass, supporting accurate weighing and preparation of calibration solutions for HPLC and related separation techniques. In environmental analysis and pesticide residue workflows, laboratories use this material to establish response factors, verify peak identity and control method performance. Supplied from manufacturer Carl ROTH, the standard integrates smoothly into routine quality-control sequences and method-validation studies where traceable chemical identity is required. Its physicochemical data facilitate solvent selection and solution preparation, while the compact glass pack size suits both single-series calibrations and longer-term reference libraries. Applications span gas and liquid chromatography in environmental monitoring, residue testing and general analytical chemistry, providing a reliable pyrimethamine source for quantitative and qualitative determinations.
This article is part of Chromatography standards (GC, HPLC, pesticides), in Analytical standards & reference materials.

Questions about Pyrimethamine, ROTICHROM® Pestilyse® HPLC, 100 mg, glass
What is this article?
Pyrimethamine, ROTICHROM® Pestilyse® HPLC, 100 mg, glass 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.
