How to Calculate Optical Purity?
Optical Purity calculator uses Optical Purity = (Observed Specific Rotation/Maximum Specific Rotation)*100 to calculate the Optical Purity, The Optical Purity formula is defined as a comparison of the optical rotation of a pure sample of unknown stereochemistry versus the optical rotation of a sample of pure enantiomer. It is a measure of the proportion of one enantiomer in a mixture of enantiomers. Optical Purity is denoted by OP symbol.
How to calculate Optical Purity using this online calculator? To use this online calculator for Optical Purity, enter Observed Specific Rotation ([α]_{obs}) & Maximum Specific Rotation ([α]_{max}) and hit the calculate button. Here is how the Optical Purity calculation can be explained with given input values -> 75 = (0.00785398163397301/0.010471975511964)*100.
