1-Ethynyl-3-methylbenzene 3-Ethynyltoluene 766-82-5 E0665 m-Tolylacetylene CAS 766-82-5

Description

As a certified reference material (CRM), 1-Ethynyl-3-methylbenzene 3-Ethynyltoluene 766-82-5 E0665 m-Tolylacetylene 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-Ethynyl-3-methylbenzene 3-Ethynyltoluene 766-82-5 E0665 m-Tolylacetylene (CAS 766-82-5), molecular formula C9H14 and molecular weight 122.21 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-Ethynyl-3-methylbenzene 3-Ethynyltoluene 766-82-5 E0665 m-Tolylacetylene (C9H14) is characterized by an organic framework. In reversed-phase chromatography, its retention is governed primarily by its non-polar molecular character, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
