{"product_id":"pcb-90-1thc-1thc","title":"PCB 90, ROTI®Star, 10 mg, glass","description":"\u003cp\u003ePCB 90 is a defined polychlorinated biphenyl congener provided as a ROTI®Star reference standard for gas-chromatographic and environmental analytical methods. It is characterised by CAS number 68194-07-0, empirical formula C₁₂H₅Cl₅ and molar mass 326,43 g\/mol, enabling unambiguous chemical identification in calibration and confirmation work. Supplied as 10 mg in glass, the solid quantity supports repeated preparation of stock and intermediate solutions for multi-point calibrations. Environmental testing laboratories rely on individual PCB congeners such as PCB 90 to map residue profiles, verify chromatographic separation and document method accuracy in soil, sediment, water and biota extracts. Single-congener standards complement technical mixtures by allowing targeted quantification and clearer peak assignment in complex chromatograms. This ROTI®Star material from manufacturer Carl ROTH is aimed at laboratories performing congener-specific PCB analysis under established GC workflows. The glass pack format facilitates secure storage and controlled aliquoting of the reference solid in daily laboratory practice.\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\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAssay (GC): ≥98 %\u003c\/li\u003e\n\u003cli\u003eCAS number: 68194-07-0\u003c\/li\u003e\n\u003cli\u003ePack size: 10 mg glass\u003c\/li\u003e\n\u003cli\u003eEG nr.: 690-263-3\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₁₂H₅Cl₅\u003c\/li\u003e\n\u003cli\u003eMolar mass: 326,43 g\/mol\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eSafety Data Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SDB-1THC-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wyOTY2NDR8YXBwbGljYXRpb24vcGRmfGFHUTVMMmd5TkM4NU1qSTFPRFEwT0RFM09UVXdMMU5FUWw4eFZFaERYMFJGWDBWT0xuQmtaZ3w2ZmNhZTcyZTJiMWE2YzU4OTU4NjYzNzU4ZDJkNWFkYTg3N2E3MmVmYWQ2Yjk4MTg3OWVlOGY4Nzc3NGEwZTI0\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"display:inline;vertical-align:middle\" 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;vertical-align:middle;border:0;\"\u003e\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Carl Roth","offers":[{"title":"10 mg \/ 1 piece","offer_id":56125706273100,"sku":"1THC.1","price":327.9,"currency_code":"EUR","in_stock":true},{"title":"10 mg \/ 6+ pieces","offer_id":56125706305868,"sku":"1THC.1","price":311.51,"currency_code":"EUR","in_stock":true},{"title":"10 mg \/ 24+ pieces","offer_id":56125706338636,"sku":"1THC.1","price":295.11,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1THC-SF-1000Wx1000H_de5e79bf-509a-4cfd-91bb-5e6d5acd4658.jpg?v=1766405286","url":"https:\/\/www.luminixhealth.com\/en-be\/products\/pcb-90-1thc-1thc","provider":"Luminix Health","version":"1.0","type":"link"}
