{"product_id":"cbesamhfpc","title":"MHFPC {Methyl Hexafluoroisopropyl Carbonate, \u003e99.5%} as Battery Electrolyte Co-Solvent and Additive, 10-50 g\/bottle, CBESAMHFPC","description":"\u003cp\u003eMethyl hexafluoroisopropyl carbonate (commonly designated as MHFPC or methyl 1,1,1,3,3,3-hexafluoro-2-propyl carbonate) is an asymmetric fluorinated organic carbonate engineered for advanced energy storage systems. By pairing a compact, electron-donating methyl group with a bulky, strongly electron-withdrawing hexafluoroisopropyl moiety, MHFPC serves as an advanced co-solvent and functional interphase-directing additive for high-voltage and high-safety lithium-ion and sodium-ion batteries.\u003c\/p\u003e\n\u003cp\u003eIts main functional roles in electrolyte engineering are: (1) \u003cstrong\u003eInterphase Engineering (SEI\/CEI)\u003c\/strong\u003e: Because of its lower reduction potential relative to standard alkyl carbonates, MHFPC 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 strong electron-withdrawing effect 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) F\u003cstrong\u003elammability Mitigation\u003c\/strong\u003e: The dense local fluorine concentration assists in suppressing burning behavior, elevating the thermal abuse threshold of the bulk liquid electrolyte formulation.\u003c\/p\u003e\n\u003cp\u003eIts main electrochemical applications are: (1) \u003cstrong\u003eHigh-Voltage Lithium-Ion Batteries\u003c\/strong\u003e: Deployed in formulations paired with high-nickel layered oxide cathodes (e.g., NMC811) to minimize transition-metal dissolution and mitigate gas evolution during high-temperature cycling. (2) \u003cstrong\u003eSilicon and Advanced Anode Integration\u003c\/strong\u003e: Assists in building resilient, elastic interphases capable of tolerating the severe volumetric shifts characteristic of silicon composite or alloy anodes.\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\u003eCBESAMHFPC (C-BESA-MHFPC)\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\u003e607382-52-5\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\u003eC₅H₄F₆O₃\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CBESAMHFPC_Structure_100x100.jpg?v=1789840364\" 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\u003e226.07 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 MHFPC 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\u003ca href=\"https:\/\/pubs.acs.org\/aamick\/article-abstract\/9\/36\/30686\/683970\/Functionality-Selection-Principle-for-High-Voltage?redirectedFrom=fulltext\"\u003e\u003cspan\u003eC.
