There are two ways to finds substances using search terms:
Search field - Substance name, CAS Registry Number, patent identifier, notes, and DOI.
Advanced Search Field(s) - Boolean operator (AND, OR, NOT) + search field values, molecular formula, experimental spectra, and the following property categories: biological/chemical, density, electrical, Lipinski, magnetic, mechanical, optical and scattering, structure related, and thermal.
You may use the search field and Advanced Search Fields separately or in combination.
For example, I'll enter the patent number WO2010071837 in the search field.
This search returns 1,157 substance results with at least one associated reference containing WO2010071837.
Next, I'll add some Advanced Search Fields:
NOT Biological > Median Lethal Dose (mg/kg): >160
AND Thermal > Melting Point (°C): <220
Check the Search key property values only box available for the below properties to focus the property query only on data found in a substance's Key Physical Properties box or preferred substance values:
Median Lethal Dose (mg/kg)
Electric Conductance (S)
Electric Conductivity (S/cm)
Electric Resistance (ohm)
Electric Resistivity (ohm*cm)
Magnetic Moment (muB)
Tensile Strength (Mpa)
Optical Rotatory Power (degrees)
Boiling Point (°C)
Glass Transition Temperature (°C)
Melting Point (°C)
The value(s) in the search field are combined with the output of the Advanced Search Fields (operators are processed in OR/AND/NOT order): WO2010071837 NOT (Median Lethal Dose (mg/kg): >160 AND Melting Point (°C): <220). Important: The first operator selected determines the relationship of Advanced Search Fields and operators to any terms entered in the search field.
You may change the order of the fields by
clicking the Drag icon
() and moving the field.
This search returns 1,122 results containing WO2010071837 that also do not have a Median Lethal Dose greater than 160 mg/kg and a Melting Point less than 220°C.
To edit the Advanced Search Fields from the results page, click the Edit Search button in the Substances search field.
