Description
Bis(2-propylheptyl) phthalate is a ROTI®Star CRM with CAS number 53306-54-0, empirical formula C₂₈H₄₆O₄, EG number 258-469-4 and a molar mass of 446,7 g/mol. The material is packed as 100 mg in a glass ampoule. Stated thermal data comprise a flash point of 220 °C and a boiling point of 252,5 to 253,4 °C. Application areas include food analysis and phthalate standards for food analysis, where this diester is required as a reference standard. Laboratories can record the CRM against its formula, molar mass and registry numbers when the 100 mg ampoule is used for analytical work. The ROTI®Star CRM from manufacturer Carl ROTH is offered in a glass ampoule, keeping the 100 mg quantity convenient for food-testing benches. Bis(2-propylheptyl) phthalate is thus specified as a phthalate reference standard with clearly stated identity C₂₈H₄₆O₄ and molar mass 446,7 g/mol. The glass-ampoule pack of 100 mg and the listed physical properties complete the description of this food-analysis CRM for professional laboratory use in phthalate standard applications.
