{"product_id":"l-proline-methyl-ester-hydrochloride-2tk5-2tk5","title":"L-Proline methyl ester hydrochloride, 100 g","description":"\u003cp\u003eL-Proline methyl ester hydrochloride is a biochemical compound with CAS number 2133-40-6 and the empirical formula C₆H₁₂ClNO₂. Its molar mass of 165,62 g\/mol provides a well-defined basis for stoichiometric calculations in synthesis and analytical work. This proline ester salt is Clear molecular identity data support method documentation and consistent transfer of procedures between teams working with amino-acid derivatives. Available from manufacturer Carl ROTH, the product aligns with chemical and biochemical catalogues focused on protected or activated proline building blocks. The hydrochloride form is a practical solid for weighing and dissolution steps common in organic and peptide-related workflows. Laboratories can use the stated molar mass and CAS reference when specifying materials in protocols, purchase records and quality documentation. quantity offers a practical balance between working volume and storage footprint for many research settings.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/fr-fr\/collections\/click-chemistry-bioconjugation-and-synthesis-reagents\"\u003eClick chemistry, bioconjugation \u0026amp; synthesis reagents\u003c\/a\u003e, in \u003ca href=\"\/fr-fr\/collections\/biochemicals-and-reagents\"\u003eBiochemicals \u0026amp; reagents\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eColour: white to off-white\u003c\/li\u003e\n\u003cli\u003eForm: powder to crystalline powder\u003c\/li\u003e\n\u003cli\u003eAssay (titr.): ≥98 %\u003c\/li\u003e\n\u003cli\u003eLoss on drying: ≤1 %\u003c\/li\u003e\n\u003cli\u003e¹H-NMR Spectrum: complies\u003c\/li\u003e\n\u003cli\u003eCAS number: 2133-40-6\u003c\/li\u003e\n\u003cli\u003ePack sizes: 100 g, 250 g, 500 g, 1 kg\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₆H₁₂ClNO₂\u003c\/li\u003e\n\u003cli\u003eMolar mass: 165,62 g\/mol\u003c\/li\u003e\n\u003cli\u003eStorage temperature: +2 to +8 °C\u003c\/li\u003e\n\u003cli\u003eProduct type: Biochemical\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-2TK5-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMzM2NHxhcHBsaWNhdGlvbi9wZGZ8YUdVMkwyZzNNQzg1TWpjeE5EQXdNelkyTVRFd0wxTlFSVnBmTWxSTE5WOUZUaTV3WkdZfGEwNmRhMzJmMWVkOTA1MjRmZTdhMzdjMzcxZjIyZmU2ZGQwZmUwZTZkMTA1OGNiN2QwOGEyYWFkNWFmMTZlMWY\" 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-2TK5-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wyNDQ1ODh8YXBwbGljYXRpb24vcGRmfGFEVmlMMmcxTkM4NU1qWTJOelU0TkRFNE5EWXlMMU5FUWw4eVZFczFYMFJGWDBWT0xuQmtaZ3wwYzM1MzEyNGUyNTYzMzk1OTRlOTMwOGFiYzJjMmRkYjQ2NjZlMDQ5NTc0YjVmNDYzYzkwYzUxYjZhYmEwNDNm\" 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":56147788464460,"sku":"2TK5.2","price":192.45,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 6+ pieces","offer_id":56147788497228,"sku":"2TK5.2","price":182.83,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 24+ pieces","offer_id":56147788529996,"sku":"2TK5.2","price":173.21,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 1 piece","offer_id":56147788562764,"sku":"2TK5.3","price":403.15,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 6+ pieces","offer_id":56147788595532,"sku":"2TK5.3","price":382.99,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 24+ pieces","offer_id":56147788628300,"sku":"2TK5.3","price":362.84,"currency_code":"EUR","in_stock":true},{"title":"500 g \/ 1 piece","offer_id":56147788661068,"sku":"2TK5.4","price":600.95,"currency_code":"EUR","in_stock":true},{"title":"500 g \/ 6+ pieces","offer_id":56147788693836,"sku":"2TK5.4","price":570.9,"currency_code":"EUR","in_stock":true},{"title":"500 g \/ 24+ pieces","offer_id":56147788726604,"sku":"2TK5.4","price":540.86,"currency_code":"EUR","in_stock":true},{"title":"1 kg \/ 1 piece","offer_id":56147788759372,"sku":"2TK5.5","price":962.15,"currency_code":"EUR","in_stock":true},{"title":"1 kg \/ 6+ pieces","offer_id":56147788792140,"sku":"2TK5.5","price":962.15,"currency_code":"EUR","in_stock":true},{"title":"1 kg \/ 24+ pieces","offer_id":56147788824908,"sku":"2TK5.5","price":962.15,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-2TK5-SF_86ec09cb-dc72-4510-9ac8-977c7cdf47ca.jpg?v=1766419487","url":"https:\/\/www.luminixhealth.com\/fr-fr\/products\/l-proline-methyl-ester-hydrochloride-2tk5-2tk5","provider":"Luminix Health","version":"1.0","type":"link"}
