Electric Literature of 5455-94-7, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 5455-94-7, Name is 2,2,5,5-Tetramethyldihydrofuran-3(2H)-one,introducing its new discovery.
New benzylcyclanone derivatives process for preparing them and cosmetic and pharmaceutical compositions containing them
The invention relates to the benzylcyclanone derivatives of formula: STR1 where R1 and R3 denote H, OH, linear or branched C1 -C8 alkyl or linear or branched C1 -C8 alkoxy, R2 and R4 represent H or OH, at least one of the two being OH, R5, R6, R7 and R8 represent H, C1 -C18 alkyl, aralkyl or aryl, it being possible for R5 and R6 and/or R7 and R8 to form an optionally substituted, saturated C5 -C12 ring, X represents O or –(CR9 R10)n with n=1 or 2 and R9 and R10 represent H or CH3 ; if X represents –(CR9 R10)n, R6 and R8, with the atoms of the ring to which they are attached, form a bicyclic system having 7 or 8 carbon atoms; if X represents –(CR9 R10)n with n=1, R9 and R10 =CH3, R5 =H and R6 and R8, with the atoms of the ring to which are attached, form a bicyclic system having 7 carbon atoms, R7 can represent a –CH2 SO3 H residue, optionally in salt form. Process for preparing these compounds and their use as antioxidants and medicinal products for the treatment of skin allergies and inflammations.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 5455-94-7, and how the biochemistry of the body works.Electric Literature of 5455-94-7
