Chloroatranorin is a member of the class of chemical compounds called depsides. Its IUPAC name is (3-hydroxy-4-methoxycarbonyl-2,5-dimethylphenyl) 5-chloro-3-formyl-2,4-dihydroxy-6-methylbenzoate. The absorbance maxima (λ max ) in the ultraviolet spectrum (in methanol solution) are 213, 252, and 282 nm .
Isotope peaks within a spectrum can help in structure elucidation. Compounds containing halogens (especially chlorine and bromine) can produce very distinct isotope peaks. The mass spectrum of methylbromide has two prominent peaks of equal intensity at m/z 94 (M) and 96 (M+2) and then two more at 79 and 81 belonging to the bromine fragment.
Electron ionization mass spectrum of toluene. Note parent peak corresponding to molecular mass M = 92 (C 7 H 8 + ) and highest peak at M-1 = 91 (C 7 H 7 + , quasi-stable tropylium cation). A mass spectrum is a histogram plot of intensity vs. mass-to-charge ratio ( m/z ) in a chemical sample, [ 1 ] usually acquired using an instrument called a ...
President Joe Biden is commuting the sentences of nearly 1,500 people and pardoning 39 others in "the largest single-day act of clemency in modern history," the White House announced Thursday. The ...
For example, the sodium benzoate is an ionic compound with the structure C 6 H 5 –CO–O − Na +, and its condensed structural formula usually written as C 6 H 5 CO 2 Na. The suffix comes from "-oic acid". The most common examples of compounds named with the "oate" suffix are esters, like ethyl acetate, CH 3 COOCH 2 CH 3.
