{"product_id":"naphthol-as-lc-2pyl-2pyl","title":"Naphthol AS-LC, min. 95 %, 10 g","description":"\u003cp\u003eNaphthol AS-LC is a substituted naphthol derivative offered at a minimum purity of 95 % for chemical and biochemical laboratory work. It is specified under CAS number 4273-92-1 with the empirical formula C₁₉H₁₆ClNO₄ and a molar mass of 357,79 g\/mol, supporting accurate identity control in synthesis and analytical documentation. The chloro- and amide-containing aromatic structure is relevant when naphthol AS-type intermediates are needed for specialty organic sequences. Defined purity and molecular data help ensure consistent batch-to-batch planning in research environments. This product is available from manufacturer Carl ROTH within a biochemicals range oriented to professional laboratory users. Handle according to standard laboratory practice for chlorinated aromatic amides and integrate the CAS number into existing reagent management systems for full traceability.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-nl\/collections\/organic-building-blocks-and-synthesis-reagents\"\u003eOrganic building blocks \u0026amp; synthesis reagents\u003c\/a\u003e, in \u003ca href=\"\/en-nl\/collections\/organic-chemicals-and-synthesis-reagents\"\u003eOrganic chemicals \u0026amp; synthesis reagents\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAssay: ≥ 95 %\u003c\/li\u003e\n\u003cli\u003eColour: reported\u003c\/li\u003e\n\u003cli\u003eForm: reported\u003c\/li\u003e\n\u003cli\u003eCAS number: 4273-92-1\u003c\/li\u003e\n\u003cli\u003ePack sizes: 10 g, 25 g, 50 g, 100 g\u003c\/li\u003e\n\u003cli\u003ePurity: min. 95 %\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₁₉H₁₆ClNO₄\u003c\/li\u003e\n\u003cli\u003eMolar mass: 357,79 g\/mol\u003c\/li\u003e\n\u003cli\u003eWeight: 0,028 kg\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-2PYL-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMjc2N3xhcHBsaWNhdGlvbi9wZGZ8YUdNMUwyZzVNaTg1TWpVME56UTNNVFEwTWpJeUwxTlFSVnBmTWxCWlRGOUZUaTV3WkdZfDRiZTc2Y2Y0ZGNmMTA4NzUzMmY4OTYyYTk4OTJmNzFlZjM5YzMzYjBmN2I0Mzc4OWY1NDFiZDUzNDIwMDczNTg\" 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-2PYL-DE-DE.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3w3ODY1MHxhcHBsaWNhdGlvbi9wZGZ8YURBd0wyZzNZaTg1TVRrMk1qWTBOVEl4TnpVNEwxTkVRbDh5VUZsTVgwUkZYMFJGTG5Ca1pnfDQ1MWFhNzc2NzY3N2E2YzA0MDBhNTZmMTAzYWE5NTU0YTdhZmRjMGE1MDg5Y2RiZTkxYWE5MjQwNTVjMzRmZDY\" 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 g \/ 1 piece","offer_id":56146227396940,"sku":"2PYL.2","price":246.2,"currency_code":"EUR","in_stock":true},{"title":"10 g \/ 6+ pieces","offer_id":56146227429708,"sku":"2PYL.2","price":233.89,"currency_code":"EUR","in_stock":true},{"title":"10 g \/ 24+ pieces","offer_id":56146227462476,"sku":"2PYL.2","price":221.58,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 1 piece","offer_id":56146227495244,"sku":"2PYL.3","price":493.45,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 6+ pieces","offer_id":56146227528012,"sku":"2PYL.3","price":468.78,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 24+ pieces","offer_id":56146227560780,"sku":"2PYL.3","price":444.11,"currency_code":"EUR","in_stock":true},{"title":"50 g \/ 1 piece","offer_id":56146227593548,"sku":"2PYL.4","price":848.2,"currency_code":"EUR","in_stock":true},{"title":"50 g \/ 6+ pieces","offer_id":56146227626316,"sku":"2PYL.4","price":805.79,"currency_code":"EUR","in_stock":true},{"title":"50 g \/ 24+ pieces","offer_id":56146227659084,"sku":"2PYL.4","price":763.38,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 1 piece","offer_id":56146227691852,"sku":"2PYL.5","price":1478.15,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 6+ pieces","offer_id":56146227724620,"sku":"2PYL.5","price":1404.24,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 24+ pieces","offer_id":56146227757388,"sku":"2PYL.5","price":1330.34,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-2PYL-SF_e20b4960-91af-4505-b202-bfdea9b416bf.jpg?v=1766419176","url":"https:\/\/www.luminixhealth.com\/en-nl\/products\/naphthol-as-lc-2pyl-2pyl","provider":"Luminix Health","version":"1.0","type":"link"}
