Chemical Structure

4-Isopropenyltoluene CAS 1195-32-0 chemical structure

Description

The occurrence of 4-Isopropenyltoluene is closely related to an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Isopropenyltoluene (CAS 1195-32-0), molecular formula C10H12 and molecular weight 132.20 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an aromatic ring system, 4-Isopropenyltoluene is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 132.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 4-Isopropenyltoluene 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.
