The E7 liquid crystal mixture has been widely used in LC devices due to its large birefringence (ca. 0.22 in the visible range) and wide nematic temperature range (approximately −10°C to 60°C). Liquid crystals such as E7 have also been explored in biosensing applications, where interactions at the LC\/aqueous interface with species such as phospholipids alter molecular alignment and produce a detectable optical signal.\u003c\/p\u003e\n\u003cdiv class=\"row display-flex\"\u003e\n\u003cdiv class=\"col-xs-12 col-md-3 text-center margin-top\"\u003e\n\u003cimg width=\"50\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0823\/0287\/files\/Ossila_Writers_Icons_Exposure.svg\" loading=\"lazy\" height=\"50\"\u003e\n\u003cp class=\"blue-heading no-margin text-center\"\u003eTerphenyl Liquid Crystal\u003c\/p\u003e\n\u003cp class=\"text-center\"\u003eWith a high transition temperature\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"col-xs-12 col-md-3 text-center margin-top\"\u003e\n\u003cimg width=\"50\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0823\/0287\/files\/versatile-icon.svg\" loading=\"lazy\" height=\"50\"\u003e\n\u003cp class=\"blue-heading no-margin text-center\"\u003eHigh Clearing Point Nematic LC\u003c\/p\u003e\n\u003cp class=\"text-center\"\u003eWide nematic temperature range\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"col-xs-12 col-md-3 text-center margin-top\"\u003e\n\u003cimg height=\"50\" loading=\"lazy\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0823\/0287\/files\/2D-Materials-Icons_-Free_ish_Shipping.svg\" width=\"50\"\u003e\n\u003cp class=\"blue-heading no-margin text-center\"\u003eSimple Worldwide Shipping\u003c\/p\u003e\n\u003cp class=\"text-center\"\u003eReliable delivery via tracked courier\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"col-xs-12 col-md-3 text-center margin-top\"\u003e\n\u003cimg width=\"50\" src=\"https:\/\/www.ossila.com\/cdn\/shop\/files\/2D-Materials-Icons_-Purity.svg\" loading=\"lazy\" height=\"50\"\u003e\n\u003cp class=\"blue-heading no-margin text-center\"\u003eHigh Purity Material\u003c\/p\u003e\n\u003cp class=\"text-center\"\u003eOver 98% purity for reliable research\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch2 id=\"product-information\"\u003eGeneral Information\u003c\/h2\u003e\n\u003chr\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth width=\"38.2%\"\u003eCAS Number\u003c\/th\u003e\n\u003ctd\u003e54211-46-0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth width=\"38.2%\"\u003eChemical Formula\u003c\/th\u003e\n\u003ctd\u003eC\u003csub\u003e24\u003c\/sub\u003eH\u003csub\u003e23\u003c\/sub\u003eN\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth width=\"38.2%\"\u003eFull Name\u003c\/th\u003e\n\u003ctd\u003e4''-Pentyl-[1,1':4',1''-terphenyl]-4-carbonitrile\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth width=\"38.2%\"\u003eMolecular Weight\u003c\/th\u003e\n\u003ctd\u003e325.45 g\/mol\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth width=\"38.2%\"\u003eMelting Point\u003c\/th\u003e\n\u003ctd\u003e128 – 130 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth width=\"38.2%\"\u003eSynonyms\u003c\/th\u003e\n\u003ctd\u003e4-Cyano-4''-n-pentyl-\u003cem\u003ep\u003c\/em\u003e-terphenyl\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth width=\"38.2%\"\u003eClassification or Family\u003c\/th\u003e\n\u003ctd\u003eLiquid crystal, Terphenylcarbonitrile, Optoelectronic materials\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eChemical Structure\u003c\/h2\u003e\n\u003chr\u003e\n\u003cfigure\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0823\/0287\/files\/4-cyano-4-pentyl-p-terphenyl-body-image.svg\" title=\"4-Cyano-4''-pentyl-p-terphenyl (5CT) CAS 54211-46-0\" rel=\"noopener noreferrer\" target=\"_blank\"\u003e\u003cimg alt=\"4-Cyano-4''-pentyl-p-terphenyl (5CT) CAS 54211-46-0\" loading=\"lazy\" width=\"320\" height=\"240\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0823\/0287\/files\/4-cyano-4-pentyl-p-terphenyl-body-image.svg\"\u003e\u003c\/a\u003e\n\u003cfigcaption\u003e4-Cyano-4''-pentyl-p-terphenyl (5CT) Chemical Structure, CAS 54211-46-0\u003c\/figcaption\u003e\n\u003c\/figure\u003e\n\u003ch2\u003eProduct Details\u003c\/h2\u003e\n\u003chr\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth width=\"38.2%\"\u003ePurity\u003c\/th\u003e\n\u003ctd\u003e\u0026gt;
