<p>Tert-Butyl 4'-methylbiphenyl-2-carboxylate is a versatile building block that can be used to synthesize complex compounds. It has CAS No. 114772-36-0 and is a fine chemical, which means it is not intended for use as a food additive, drug or cosmetic ingredient. Tert-Butyl 4'-methylbiphenyl-2-carboxylate is also a reagent, speciality chemical and useful scaffold for the synthesis of pharmaceuticals, pesticides and other chemicals.</p>

<p>1-Phenoxyphthalazine is a n-oxide with life-threatening properties. It is used as a medication for high blood pressure and as an anxiolytic. 1-Phenoxyphazin has been shown to have receptor affinity for the dopamine, serotonin, and noradrenaline receptors. It also blocks the carboxylate ion channels of the central nervous system. 1-Phenoxyphthalazine has been shown to have peroxide and chloride properties, which may contribute to its antihypertensive effects.</p>

<p>5-Methyl-2,3-hexanedione is a chemical compound that has been shown to be effective against avian influenza and the influenza virus. 5-Methyl-2,3-hexanedione inhibits the growth of influenza viruses by binding to the virus particles and preventing them from attaching to cells in the respiratory tract. This chemical also prevents the release of infectious viral particles from infected cells. The rate of encapsulation was determined by measuring the amount of 5-methyl-2,3-hexanedione that was adsorbed onto tylosin particles in a plate test. The encapsulation rate is greater than 80%. 5-Methyl-2,3-hexanedione has also been shown to inhibit tylosin resistance in vitro.</p>
