Boiling Point Classification

Boiling Point Classification refers to the temperature ranges at which cannabis terpenes and cannabinoids vaporize, a critical framework for breeding and extraction work. Terpenes typically volatilize between 150–250°C, while cannabinoids like THC and CBD have boiling points around 157°C and 160–180°C respectively. This classification system helps breeders predict how compounds will behave under heat, inform processing methods, and evaluate preservation challenges during storage and transport. Understanding boiling-point profiles is foundational for breeders developing strains suited to specific extraction or vaporization technologies. Lineage records and lab analysis increasingly document these thermal properties to support reproducibility across generations.

Breeders use boiling-point data to select parent plants likely to retain desirable terpene and cannabinoid profiles under processing conditions. Cultivars bred for specific end-use markets—live resin, distillation, or vape products—often prioritize genetics with stable compound volatility in target temperature windows.
