Beschrijving
Undecyl dodecyl phthalate is a ROTI®Star CRM reference standard with CAS number 68515-47-9, supplied as 100 mg in glass for laboratory food analysis. This mixed alkyl phthalate ester has a density of 0,95 g/cm³, a flash point of 274 °C and a boiling point above 400 °C. Such physical data inform handling assessments and the preparation of calibration solutions for chromatographic work. Phthalate standards of this type are used in food analysis to identify and quantify phthalate plasticisers in complex matrices. The material is available from manufacturer Carl ROTH in the ROTI®Star CRM series of reference standards for food analysis. The 100 mg glass pack is suited to method development, calibration series and quality-control samples where only small quantities of standard are required. Undecyl dodecyl phthalate complements other phthalate reference substances in food-control laboratories, covering mixed C₁₁/C₁₂ ester species that may occur as plasticiser-related residues. Typical laboratory use includes gravimetric or volumetric preparation of working solutions and comparison of chromatographic retention under the chosen analytical conditions.
