The number before the resorcinol symbols in the description of the molecular structure indicates the number of the corresponding resorcinol moieties or oxidation products in the molecule; O indicates C-O coupling (grey background); qqq marks the third quinoid structure in the molecule; confirmed molecular formulas
with mass accuracy < 5 ppm are in bold; nd--not detected; dna--data not analysed.
The mass spectra of compound 19a showed molecular ion peak at m/z (302) which is in agreement with its molecular formula
Each monograph has information on its names, category, molecular formula
and weight, appearance, solubilities, and other chemistry, and methods, including the analytical system components, major operating parameters, standard solution and sample preparations, correlation coefficient and linearity, coefficient of variation of the assay, limit of detection and quantification, and interference.
Folic acid's molecular formula
is C19, H19, N7, 06.
The numbers indicate the position in which the group is attached; the groups and molecular formula
Next, tocopherols do have stereoisomers, which have the same molecular formula
but differ configurationally based on the direction of the methyl groups at chiral carbon atoms, the isomers are designated 2R, 4'R, 8'R; 2S, 4'R, 8'R; 2RS, 4'R, 8'R; 2R, 4'RS, 8'RS; 2S, 4'RS, 8'RS and rotate polarized light to varying degrees.
The question dealt with the molecular formula
for cyclohexanol, which North Hollywood gave as C6 H12 O.
There is a "slim chance," he told SCIENCE NEWS, that the compound isolated from human plasma is not ouabain itself but an isomer -- a substance sharing the same molecular formula
but varying slightly in its three-dimensional structure.
