{"product_id":"methylene-green-2phx-2phx","title":"Methylene green, min. 95 %, 5 g","description":"\u003cp\u003eMethylene green is a dye-grade chemical offered at a minimum purity of 95 % for laboratory and biochemical applications. It is listed under CAS number 2679-01-8 and has a molar mass of 364,85 g\/mol, giving essential identity parameters for documentation, weighing, and experimental design. The stated assay and molar mass support consistent preparation of solutions and reproducible laboratory practice. This product is available from manufacturer Carl ROTH in the fine-chemical and biochemical segment. Clear CAS and purity information help users select methylene green alongside other specialty reagents without relying on unverified performance claims. quantity is practical for method trials, teaching laboratories, and low-consumption research, while the manufacturer’s molar-mass value assists accurate mass-to-mole conversions in chemical and life-science settings.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/fr-fr\/collections\/organic-building-blocks-and-synthesis-reagents\"\u003eOrganic building blocks \u0026amp;
