1,2-diethynyl-4,5-dimethoxybenzene CAS 170160-98-2

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-diethynyl-4,5-dimethoxybenzene.

1,2-diethynyl-4,5-dimethoxybenzene (CAS 170160-98-2) is a high-purity analytical reference standard with the molecular formula C12H10O2 and a molecular weight of 186.21 g/mol.

Structurally, 1,2-diethynyl-4,5-dimethoxybenzene (C12H10O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 186.21 g/mol, it falls into the medium-molecular-weight range. 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.
