Chemical Structure

1,3-Dimethyl-5-vinylbenzene CAS 5379-20-4 chemical structure

Description

As a certified reference material (CRM), 1,3-Dimethyl-5-vinylbenzene 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.

1,3-Dimethyl-5-vinylbenzene (CAS 5379-20-4), molecular formula C10H12 and molecular weight 132.20 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1,3-Dimethyl-5-vinylbenzene (C10H12) contains an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 132.20 g/mol, it falls into the low-molecular-weight range. 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.
