Offered as 100 mg in glass, this disodium salt of phthalic acid is intended for food analysis and related laboratory applications that require a defined phthalate identity. Its molar mass is 210,09 g\/mol and its density is 1,67 g\/cm³, supporting gravimetric preparation of stock and working solutions. Analytical laboratories use phthalate reference standards of this type in chromatographic methods for the identification and quantification of phthalates in food matrices. The product comes from manufacturer Carl ROTH as part of the ROTI®Star CRM range of reference standards for food analysis. The 100 mg glass presentation is practical for calibration, method development, and quality-control work where only small amounts of standard are needed. Disodium phthalate sits among other phthalate standards used in food-control workflows, providing the salt form of phthalic acid as a complementary reference substance. Typical use includes preparation of calibration series and confirmation of retention or spectral characteristics under the chosen laboratory method.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCAS number: 15968-01-1\u003c\/li\u003e\n\u003cli\u003ePack size: 100 mg glass\u003c\/li\u003e\n\u003cli\u003eEG nr.: 240-106-6\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₈H₄Na₂O₄\u003c\/li\u003e\n\u003cli\u003eMolar mass: 210,09 g\/mol\u003c\/li\u003e\n\u003cli\u003eStorage temperature: +2 to +8 °C\u003c\/li\u003e\n\u003cli\u003eUNSPSC: 41116107\u003c\/li\u003e\n\u003cli\u003eSafety Data Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/www.carlroth.com\/downloads\/sdb\/DE\/2\/SDB_291G_DE_EN.pdf\" target=\"_blank\" rel=\"noopener noreferrer\" 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-block;vertical-align:middle;border:0;\"\u003e\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Luminix Health","offers":[{"title":"100 mg","offer_id":58656472531276,"sku":"291G.1","price":134.3,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/291G-1.jpg?v=1788331459","url":"https:\/\/www.luminixhealth.com\/fr-fr\/products\/disodium-phthalate-roti-star-crm-100-mg-glass-291g","provider":"Luminix Health","version":"1.0","type":"link"}
