{"product_id":"pararosaniline-hydrochloride-2t81-2t81","title":"Pararosaniline hydrochloride, 100 g","description":"\u003cp\u003ePararosaniline hydrochloride is an organic dye salt with CAS number 569-61-9, empirical formula C₁₉H₁₇N₃ClH and molar mass 323,82 g\/mol. The hydrochloride form offers convenient solid handling for weighing into buffer systems, staining baths or intermediate preparations. Research and quality-control groups use pararosaniline derivatives in histology-related protocols, colour-forming reactions and method development where a stable cationic dye salt is preferred. Material from manufacturer Carl ROTH arrives ready for cold storage according to the stated temperature requirement and for integration into established laboratory workflows. Clear identity data (CAS, formula and molar mass) support documentation, risk assessment and batch traceability. Appropriate personal protective equipment, ventilation and waste controls for organic dye salts should be applied during routine use.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-nl\/collections\/inorganic-salts\"\u003eInorganic salts\u003c\/a\u003e, in \u003ca href=\"\/en-nl\/collections\/inorganic-chemicals\"\u003eInorganic chemicals\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eColour: purple to green to dark green to dark gray to black\u003c\/li\u003e\n\u003cli\u003eForm: solid\u003c\/li\u003e\n\u003cli\u003e¹H-NMR Spectrum: complies\u003c\/li\u003e\n\u003cli\u003eCAS number: 569-61-9\u003c\/li\u003e\n\u003cli\u003ePack sizes: 100 g, 250 g, 500 g, 1 kg\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₁₉H₁₇N₃ClH\u003c\/li\u003e\n\u003cli\u003eMolar mass: 323,82 g\/mol\u003c\/li\u003e\n\u003cli\u003eStorage temperature: -20 °C\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-2T81-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMTU1OHxhcHBsaWNhdGlvbi9wZGZ8YUdZMEwyZ3lNUzg1TWpVME56VXhPVGt6T0RnMkwxTlFSVnBmTWxRNE1WOUZUaTV3WkdZfGExODNkZTI5ZWY2MDk1YWY2ZTRmYTA2MDQ2N2YwY2ZmZjllNzdlNWM1OTNjNDRmMzY1MDQ3OTA4YmViNjAzNDg\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"display:inline;vertical-align:middle\" title=\"Technical sheet PDF\" aria-label=\"Technical sheet 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\u003cli class=\"lx-tis-li\"\u003eSafety Data Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SDB-2T81-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wyNjg2ODB8YXBwbGljYXRpb24vcGRmfGFEQXpMMmhrTkM4NU1qQTJORFkxTnpJME5EUTJMMU5FUWw4eVZEZ3hYMFJGWDBWT0xuQmtaZ3w2NzRlYzFjNGRjNzg1NzlmNTMxYTNlNmY2OWY5NjViZjdkOTU1ZTEzNmM1NjA1NWI1ZmQ5NjdjN2ZiOWVkMjU5\" 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":"100 g \/ 1 piece","offer_id":56146286608716,"sku":"2T81.2","price":203.2,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 6+ pieces","offer_id":56146286641484,"sku":"2T81.2","price":193.04,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 24+ pieces","offer_id":56146286674252,"sku":"2T81.2","price":182.88,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 1 piece","offer_id":56146286707020,"sku":"2T81.3","price":413.9,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 6+ pieces","offer_id":56146286739788,"sku":"2T81.3","price":393.21,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 24+ pieces","offer_id":56146286772556,"sku":"2T81.3","price":372.51,"currency_code":"EUR","in_stock":true},{"title":"500 g \/ 1 piece","offer_id":56146286805324,"sku":"2T81.4","price":779.4,"currency_code":"EUR","in_stock":true},{"title":"500 g \/ 6+ pieces","offer_id":56146286838092,"sku":"2T81.4","price":740.43,"currency_code":"EUR","in_stock":true},{"title":"500 g \/ 24+ pieces","offer_id":56146286870860,"sku":"2T81.4","price":701.46,"currency_code":"EUR","in_stock":true},{"title":"1 kg \/ 1 piece","offer_id":56146286903628,"sku":"2T81.5","price":1284.65,"currency_code":"EUR","in_stock":true},{"title":"1 kg \/ 6+ pieces","offer_id":56146286936396,"sku":"2T81.5","price":1284.65,"currency_code":"EUR","in_stock":true},{"title":"1 kg \/ 24+ pieces","offer_id":56146286969164,"sku":"2T81.5","price":1284.65,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-2T81-SF_e6894ee1-923d-444d-baba-96ecfbceb0b6.jpg?v=1766419285","url":"https:\/\/www.luminixhealth.com\/en-nl\/products\/pararosaniline-hydrochloride-2t81-2t81","provider":"Luminix Health","version":"1.0","type":"link"}
