β-Pinene is a monoterpene hydrocarbon reference substance in ROTICHROM® GC quality intended for gas chromatography. It is identified by CAS number 127-91-3 and empirical formula C₁₀H₁₆, with a molar mass of 136,24 g/mol and a density of 0,87 g/cm³. The boiling range spans 169 to 179 °C and the flash point is 39 °C, informing handling and chromatographic conditions. This 1 g glass pack supplies a larger reference amount for calibration series, system suitability checks and routine peak confirmation of pinene-related analytes. Laboratories in flavour, fragrance, resin and essential-oil analysis rely on defined β-pinene standards when building GC methods or verifying library matches. The material is available from manufacturer Carl ROTH within the ROTICHROM® GC line for reference substances. EG number 204-872-5 supports regulatory labelling and documentation. Physical constants and the glass presentation make the product straightforward to integrate into analytical reference collections. It suits GC workflows that require consistent monoterpene identity standards at gram scale. This article is part of Essential oils & fragrances, in Natural products & essential oils.
