Description
Dimethyl phthalate is a ROTI®Star CRM reference substance for gas chromatography, defined by CAS number 131-11-3, empirical formula C₁₀H₁₀O₄ and EG number 205-011-6. This aromatic diester has a molar mass of 194,18 g/mol, a density of 1,194 g/cm³, a flash point of 154 °C and a boiling point of 283,1 °C, giving a documented physicochemical profile for method setup. The product is packed as 500 mg in a glass ampoule, a format suited to accurate weighing when preparing calibration solutions. In GC laboratories it serves as a reference compound for retention comparison and related phthalate analyses. Physical constants such as density and boiling point help analysts set injection temperatures and column programmes. The ROTI®Star CRM material from manufacturer Carl ROTH belongs to the range of reference substances used in gas chromatography. The glass ampoule presentation keeps the 500 mg quantity ready for transfer into volumetric glassware. Documented identity, molar mass and thermal data support use of this dimethyl phthalate in chromatography, method validation and inter-laboratory comparison work.
