Chemical Structure
Description
The occurrence of 3-Isopropyl styrene is closely related to an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Isopropyl styrene (CAS 19789-34-5), molecular formula C11H14 and molecular weight 146.23 g/mol, is a CATO reference standard with documented purity and traceability.
3-Isopropyl styrene (C11H14) contains an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 3-Isopropyl styrene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
