Chemical Structure

1,2-Di-m-tolylethyne CAS 2765-16-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,2-Di-m-tolylethyne.

CATO supplies 1,2-Di-m-tolylethyne (CAS 2765-16-4), a certified reference material (molecular formula C16H14, MW 206.28 g/mol) for analytical method development and quality control.

Based on its molecular formula C16H14, 1,2-Di-m-tolylethyne contains a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 206.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
