{"product_id":"cbesaehfpc","title":"EHFPC {Ethyl Hexafluoroisopropyl Carbonate, \u003e99.5%} as Battery Electrolyte Co-Solvent and Additive, 10-50 g\/bottle, CBESAEHFPC","description":"\u003cp\u003eEthyl hexafluoroisopropyl carbonate (commonly designated as EHFPC or ethyl 1,1,1,3,3,3-hexafluoro-2-propyl carbonate) is an asymmetric fluorinated organic carbonate that bridges standard linear alkyl carbonates with heavily fluorinated structures. By pairing a traditional ethyl group with a bulky, electron-withdrawing hexafluoroisopropyl moiety, EHFPC functions as an advanced co-solvent and functional interphase-directing additive for high-voltage and high-safety lithium-ion and sodium-ion systems.\u003c\/p\u003e\n\u003cp\u003eIts main functional roles in electrolyte engineering are: (1) \u003cstrong\u003ePassivation \u0026amp; Interphase Engineering (SEI\/CEI)\u003c\/strong\u003e: Due to its lowered reduction potential, EHFPC undergoes preferential reductive decomposition during initial electrochemical formation. This pathway promotes the precipitation of a stable, inorganic-rich Solid Electrolyte Interphase (SEI) containing metal fluorides (LiF \/ NaF) that suppress continuous electrolyte consumption. (2) \u003cstrong\u003eOxidative Stability for High-Voltage Cathodes\u003c\/strong\u003e: The electron-withdrawing nature of the hexafluoroisopropyl chain deactivates the central carbonyl group against electrophilic attack and premature oxidation, raising the anodic stability ceiling for cells operating above 4.3 V–4.5 V. (3) \u003cstrong\u003eFlammability Mitigation\u003c\/strong\u003e: The incorporation of dense fluorine fractions reduces the overall heat release rate and helps elevate the thermal abuse threshold of the bulk liquid electrolyte.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 283.6px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.7019%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9772%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCBESAEHFPC (C-BESA-EHFPC)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.7019%; height: 35.6px;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9772%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e18925-64-9\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 102px;\"\u003e\n\u003ctd style=\"width: 33.7019%; height: 102px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9772%; height: 102px;\"\u003e\n\u003cp\u003e\u003cspan\u003eC\u003csub\u003e6\u003c\/sub\u003e\u003c\/span\u003e\u003cspan\u003eH\u003c\/span\u003e\u003csub\u003e6\u003c\/sub\u003e\u003cspan\u003eF\u003c\/span\u003e\u003csub\u003e6\u003c\/sub\u003e\u003cspan\u003eO\u003c\/span\u003e\u003csub\u003e3\u003c\/sub\u003e\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CBESAEHFPC_Structure_100x100.jpg?v=1789806976\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.7019%; height: 35.6px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9772%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eColorless Liquid\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.7019%; height: 35.6px;\"\u003e\n\u003cstrong\u003e \u003c\/strong\u003e\u003cem\u003ePurity\u003c\/em\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 65.9772%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;99.5% (Battery Grade)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 33.7019%; height: 19.6px;\"\u003e\u003cem\u003eMolecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9772%; height: 19.6px;\"\u003e\u003cspan\u003e240.1 g\/mol\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 33.7019%; height: 19.6px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9772%; height: 19.6px;\"\u003e\u003cspan\u003e10 g, 25 g, and 50 g\/bottle\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e: Please store the EHFPC in the glovebox due to its sensitivity to humidity and oxygen.\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e: \u003c\/span\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\u003cspan\u003e\u003ca href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S1452398123021089\"\u003eT.
