Beschreibung
Bis(2-butoxyethyl) phthalate is a ROTI®Star CRM with CAS number 117-83-9 and empirical formula C₂₀H₃₀O₆. This phthalate diester is supplied as a 100 mg quantity in glass for use as a ROTI®Star CRM in analytical laboratories. The molar mass is 366,4 g/mol and the flash point is 205 °C, values that help when planning handling, dissolution and the preparation of calibration solutions. From manufacturer Carl ROTH, the ROTI®Star CRM presentation supports identification and quantification work in which bis(2-butoxyethyl) phthalate is required as a discrete standard. The 100 mg glass pack provides enough material for several stock solutions while remaining compact for a reference inventory. Analysts weigh only the aliquot needed for each series, which suits method development, instrument calibration and quality-control sequences. The 2-butoxyethyl substitution pattern sets this analogue apart from simple dialkyl phthalates, so a dedicated CRM is valuable when that specific structure must be confirmed. With documented formula, molar mass and flash point, the 100 mg unit is a practical choice for organic trace analysis involving this ester.
