Its primary application is in medicine, where it is used as a diagnostic dye. Methylene blue is used to stain microscope slides, allowing doctors and scientists to observe tissues and cells under a microscope. This allows them to accurately identify various pathologies and diseases. Methylene blue is also used in the pharmaceutical industry as an ingredient in some medicines. It possesses antibacterial and antiparasitic properties and is therefore used to treat various infections and diseases, such as malaria and urinary tract infections. Another use of methylene blue is in the food industry. It is added to some foods as a dye to give them an attractive color. It can be used in beverages, candies, ice cream, and many other food products. Methylene blue is also used in the textile industry, where it is used to dye fabrics. Due to its durability and color intensity, it is often used to create various patterns and effects on fabrics. In summary, methylene blue is a versatile chemical product used in the medical, pharmaceutical, food, and textile industries. Its coloring and antibacterial properties make it extremely useful in many fields and industries.","brand":"WARCHEM","offers":[{"title":"Default Title","offer_id":46855195033948,"sku":"5902729731546","price":4.69,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0693\/0491\/0119\/products\/10528.jpg?v=1688110570"},{"product_id":"methylenblau-losung-0-1-rein-100-ml-biolaboratorium","title":"METHYLENE BLUE solution 0.1% – pure 100 ml BIOLABORATORIUM","description":"\u003cp\u003e\u003cstrong\u003eMethylene Blue Solution 0.1% - pure\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eTechnical information about chemical reagents:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eChemical formula: C₁₆H₁₈ClN₃S\u003c\/li\u003e\n  \u003cli\u003eCAS number: 61-73-4\u003c\/li\u003e\n  \u003cli\u003eEC number: 200-515-2\u003c\/li\u003e\n  \u003cli\u003eSynonyms: aqueous methylene blue solution\u003c\/li\u003e\n  \u003cli\u003eSpecies: pure\u003c\/li\u003e\n  \u003cli\u003ePurity: dye content min. 96%\u003c\/li\u003e\n  \u003cli\u003eSolution concentration: 0.1%\u003c\/li\u003e\n  \u003cli\u003eMolar mass: 319.88 g\/mol\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eExamples of professional applications in various industries:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMicroscopy:\u003c\/strong\u003e Staining of tissues and biological specimens to improve visibility of cell structures.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMicrobiology:\u003c\/strong\u003e Identification and differentiation of bacterial species in microbiological tests.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScientific research\u003c\/strong\u003e: Use in chemical and biochemical analyses as an indicator dye.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eHazard statements on the product label:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\n \u003cstrong\u003eH302:\u003c\/strong\u003e Harmful if swallowed.\u003cbr\u003e\n \u003cstrong\u003eH319:\u003c\/strong\u003e Causes serious eye irritation.\u003cbr\u003e\n \u003cstrong\u003eH335:\u003c\/strong\u003e May cause respiratory irritation.\u003cbr\u003e\n \u003cstrong\u003eH410:\u003c\/strong\u003e Very toxic to aquatic life with long-lasting effects.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSafety statements on the product label:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\n \u003cstrong\u003eP261:\u003c\/strong\u003e Avoid breathing dust\/fume\/gas\/mist\/vapors\/spray.\u003cbr\u003e\n \u003cstrong\u003eP264:\u003c\/strong\u003e Wash hands thoroughly after handling.\u003cbr\u003e\n \u003cstrong\u003eP273:\u003c\/strong\u003e Avoid release to the environment.\u003cbr\u003e\n \u003cstrong\u003eP280:\u003c\/strong\u003e Wear protective gloves\/protective clothing\/eye protection\/face protection.\u003cbr\u003e\n \u003cstrong\u003eP301 + P312\u003c\/strong\u003e: IF SWALLOWED: Call a POISON CENTER\/doctor if you feel unwell.\u003cbr\u003e\n \u003cstrong\u003eP305 + P351 + P338:\u003c\/strong\u003e IF IN EYES: Rinse cautiously with water for several minutes.
