{"product_id":"clarithromycin-2h63-2h63","title":"Clarithromycin, min. 95 %, EP Impurity A, 500 µg","description":"\u003cp\u003eClarithromycin, min. 95 %, EP Impurity A is a defined impurity reference material for analytical and pharmaceutical research. It carries CAS number 124412-58-4, the empirical formula C₃₈H₆₉NO₁₄, and a molar mass of 763,95 g\/mol. With a stated minimum purity of 95 %, this EP Impurity A grade supports method development, impurity profiling, and chromatographic system suitability work related to macrolide antibiotics. size is practical for calibration, spike-recovery experiments, and limited-quantity reference use in quality-control and R\u0026amp;D laboratories. Analysts can rely on the clear chemical identity data when preparing standards and documenting results. The material is supplied from manufacturer Carl ROTH within the impurities and biochemicals offering and is intended for professional laboratory applications. Consistent labelling of CAS, formula, and purity grade simplifies inventory management and regulatory documentation in impurity-related studies.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-be\/collections\/chromatography-standards\"\u003eChromatography standards (GC, HPLC, pesticides)\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\u003eCAS number: 124412-58-4\u003c\/li\u003e\n\u003cli\u003ePack sizes: 500 µg, 1 mg, 2 mg, 5 mg, 10 mg\u003c\/li\u003e\n\u003cli\u003ePurity: min. 95 %\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₃₈H₆₉NO₁₄\u003c\/li\u003e\n\u003cli\u003eMolar mass: 763,95 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-2H63-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMzE4N3xhcHBsaWNhdGlvbi9wZGZ8YURGaUwyaGxNaTg1TWpVME5qZzJNamswTURRMkwxTlFSVnBmTWtnMk0xOUZUaTV3WkdZfGRiMzRkODk0NWFiNjAzNmIxMGVmNTBlMDZhOTM4MzhjMDI2YjQ5NDE4OWY2ODY4OWUwOWJhZTQ4NzY0YzIwMjg\" 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\u003c\/ul\u003e","brand":"Carl Roth","offers":[{"title":"1 mg \/ 1 piece","offer_id":56136688009548,"sku":"2H63.2","price":1073.95,"currency_code":"EUR","in_stock":true},{"title":"1 mg \/ 6+ pieces","offer_id":56136688042316,"sku":"2H63.2","price":1020.25,"currency_code":"EUR","in_stock":true},{"title":"1 mg \/ 24+ pieces","offer_id":56136688075084,"sku":"2H63.2","price":966.56,"currency_code":"EUR","in_stock":true},{"title":"2 mg \/ 1 piece","offer_id":56136688107852,"sku":"2H63.3","price":1714.65,"currency_code":"EUR","in_stock":true},{"title":"2 mg \/ 6+ pieces","offer_id":56136688140620,"sku":"2H63.3","price":1628.92,"currency_code":"EUR","in_stock":true},{"title":"2 mg \/ 24+ pieces","offer_id":56136688173388,"sku":"2H63.3","price":1543.19,"currency_code":"EUR","in_stock":true},{"title":"5 mg \/ 1 piece","offer_id":56136688206156,"sku":"2H63.4","price":2854.15,"currency_code":"EUR","in_stock":true},{"title":"5 mg \/ 6+ pieces","offer_id":56136688238924,"sku":"2H63.4","price":2711.44,"currency_code":"EUR","in_stock":true},{"title":"5 mg \/ 24+ pieces","offer_id":56136688271692,"sku":"2H63.4","price":2568.74,"currency_code":"EUR","in_stock":true},{"title":"10 mg \/ 1 piece","offer_id":56136688304460,"sku":"2H63.5","price":3563.65,"currency_code":"EUR","in_stock":true},{"title":"10 mg \/ 6+ pieces","offer_id":56136688337228,"sku":"2H63.5","price":3385.47,"currency_code":"EUR","in_stock":true},{"title":"10 mg \/ 24+ pieces","offer_id":56136688369996,"sku":"2H63.5","price":3207.29,"currency_code":"EUR","in_stock":true},{"title":"500 µg \/ 1 piece","offer_id":56136688402764,"sku":"2H63.1","price":686.95,"currency_code":"EUR","in_stock":true},{"title":"500 µg \/ 6+ pieces","offer_id":56136688435532,"sku":"2H63.1","price":652.6,"currency_code":"EUR","in_stock":true},{"title":"500 µg \/ 24+ pieces","offer_id":56136688468300,"sku":"2H63.1","price":618.26,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-2H63-SF_9e83a513-3c10-44c7-8252-80c80da4ec31.jpg?v=1766417421","url":"https:\/\/www.luminixhealth.com\/en-be\/products\/clarithromycin-2h63-2h63","provider":"Luminix Health","version":"1.0","type":"link"}
