|CDX Constant Name:||kCDXProp_Bond_CIPStereochemistry|
|CDX Constant Value:||0x060A|
|Property of objects:||kCDXObj_Bond|
|First written/read in:||ChemDraw 6.0|
The bond's absolute stereochemistry according to the Cahn-Ingold-Prelog system.
ChemDraw will preserve any value present in a file without confirming its accuracy -- as long as the structure is not edited in ChemDraw. Any change to a structure has the potential of changing its stereochemical descriptors, and so ChemDraw will recalculate the structure's chemistry after any change. As a practical matter, we are very confident about the accuracy of ChemDraw's calculation of stereochemical descriptors, so this behavior should rarely cause problems.
The Cahn-Ingold-Prelog system for describing absolute stereochemistry is defined in the following references:
This is an enumerated property. Acceptible values are shown in the following list:
|1||N||Determined to be symmetric|
If this property is absent:
The bond is treated as having Undetermined stereochemistry.
