It is possible to search compounds by the number they have of different types of Carbon (C, CH, CH2, CH3). In the search, you can also establish the number of carbons connected to Oxigens and Nitrogens, together with the number of heteroatoms.
A specific number for each type of atom or an interval can also be specified, as it has a bar system with two markers to establish the interval in a quick and easy way.
The search is very easy to configure. You only need to press the "Configure" button. A new window will appear. Insert the number of bars to define the type of atoms to be searched and another window will come up. This one is to establish the carbon type and the heteroatoms by which the search has to be carried out. This option can be established only for the skeleton of the compound or for the whole structure of the compound.The available atom types are:
SKELETON: C*, CH*, CH2*, CH3*, C-O*, CH-O*, CH2-O* y CH3-O*
WHOLE STRUCTURE: C, CH, CH2, CH3, C-O, CH-O, CH2-O, CH3-O, Br, Cl, F, H, I, N, O, P and S
Atom type: C* Interval: 0-5
Atom type: CH* Interval: 4-4
