Description

24599-58-4 QK260AXY6T 2,5-Dimethoxytoluene Benzene, 1,4-dimethoxy-2-methyl- 1,4-Dimethoxy-2-methylbenzene EINECS 246-343-1 Methyl hydroquinone dimethyl ester 2-Methylhydroquinone dimethyl ether NSC 149950 Toluene, 2,5-dimethoxy- UNII-QK260AXY6T (CAS 24599-58-4) is a high-purity analytical reference standard with the molecular formula C9H18O2 and a molecular weight of 158.24 g/mol.

The molecular framework of 24599-58-4 QK260AXY6T 2,5-Dimethoxytoluene Benzene, 1,4-dimethoxy-2-methyl- 1,4-Dimethoxy-2-methylbenzene EINECS 246-343-1 Methyl hydroquinone dimethyl ester 2-Methylhydroquinone dimethyl ether NSC 149950 Toluene, 2,5-dimethoxy- UNII-QK260AXY6T (C9H18O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.
