{"product_id":"pcb-197-1tph-1tph","title":"PCB 197, ROTI®Star, 5 mg, glass","description":"\u003cp\u003ePCB 197 is a polychlorinated biphenyl congener supplied as a ROTI®Star reference material for environmental and chromatographic analysis. With CAS number 33091-17-7 and empirical formula C₁₂H₂Cl₈, this octachlorobiphenyl has a molar mass of 429,77 g\/mol and serves laboratories that need defined PCB standards for calibration, peak assignment, and quantitative work. It is particularly relevant to gas chromatography methods used in monitoring persistent organic pollutants. Packaged as 5 mg in glass, the neat material supports flexible preparation of stock and dilution series under laboratory-controlled conditions. PCB 197 from manufacturer Carl ROTH belongs to the ROTI®Star range and is aimed at professional users in environmental analysis, residue testing, and related GC applications. Documented identity parameters assist traceability when laboratories assemble multi-congener calibration mixes or check separation performance for highly chlorinated biphenyls. This reference substance integrates readily into routine quality-control schemes and research protocols that depend on discrete, well-characterised PCB congeners for reliable analytical results.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-be\/collections\/icp-aas-and-ion-standards\"\u003eICP, AAS \u0026amp; ion standards\u003c\/a\u003e, in \u003ca href=\"\/en-be\/collections\/analytical-standards-and-reference-materials\"\u003eAnalytical standards \u0026amp; reference materials\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAssay (GC): ≥98 %\u003c\/li\u003e\n\u003cli\u003eCAS number: 33091-17-7\u003c\/li\u003e\n\u003cli\u003ePack size: 5 mg glass\u003c\/li\u003e\n\u003cli\u003eEG nr.: 690-136-2\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₁₂H₂Cl₈\u003c\/li\u003e\n\u003cli\u003eMolar mass: 429,77 g\/mol\u003c\/li\u003e\n\u003cli\u003eSafety Data Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SDB-1TPH-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wyOTY2ODB8YXBwbGljYXRpb24vcGRmfGFHRXhMMmc0WlM4NU1qSTJPREUzTnpNeU5qTTRMMU5FUWw4eFZGQklYMFJGWDBWT0xuQmtaZ3w5MGI1N2EzNTFlNzA0OGMwOGI0MTAxYjBjY2M4ZDQ3ZmEwOGY5YTk4YmVjMWY2NjIyNjkxNWE3ODdiYTE0MDhj\" target=\"_blank\" rel=\"noopener noreferrer\" title=\"SDS PDF\" aria-label=\"SDS PDF\"\u003e\u003cimg class=\"sds-icon\" src=\"https:\/\/img.icons8.com\/color\/48\/pdf.png\" alt=\"PDF\" width=\"18\" height=\"18\" style=\"width:18px;height:18px;max-width:18px;margin:0;padding:0;display:inline-block;vertical-align:middle;border:0;\"\u003e\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Carl Roth","offers":[{"title":"5 mg \/ 1 piece","offer_id":56125717086540,"sku":"1TPH.1","price":482.7,"currency_code":"EUR","in_stock":true},{"title":"5 mg \/ 6+ pieces","offer_id":56125717119308,"sku":"1TPH.1","price":458.57,"currency_code":"EUR","in_stock":true},{"title":"5 mg \/ 24+ pieces","offer_id":56125717152076,"sku":"1TPH.1","price":434.43,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1TPH-SF-1000Wx1000H_4211a119-f483-47d2-b105-7ac099884ac1.jpg?v=1766405338","url":"https:\/\/www.luminixhealth.com\/en-be\/products\/pcb-197-1tph-1tph","provider":"Luminix Health","version":"1.0","type":"link"}
