Chemical context

CAS68845-00-1
Chemical name(+-)-2-Ethoxy-2,6,6-trimethyl-9-methylenebicyclo[3.3.1]nonane
FormulaC15H26O
Molecular weight223 g/mol
Vapour pressure0.00992 Pa at 20 °C (0.0099 Pa)
Relative VP bandvery_low

The Pa value is a unit conversion only, not a temperature normalisation. VP band and molecular weight are not translated into evaporation hours.

At 20 °C, a vapor pressure of 0.00992 Pa (≈ 9.920e-3 Pa) was reported; relative physical band class: very_low. This is not a prediction of evaporation time, odor strength, diffusion, or skin/blotter duration.
