Description

1,2-bis(4-methylphenyl)ethane-1,2-dione 1,2-ethanedione, 1,2-bis(4-methylphenyl)- 3457-48-5 InChI=1/C16H14O2/c1-11-3-7-13(8-4-11)15(17)16(18)14-9-5-12(2)6-10-14/h3-10H,1-2H (CAS 3457-48-5), molecular formula C16H26O2 and molecular weight 250.38 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C16H26O2, 1,2-bis(4-methylphenyl)ethane-1,2-dione 1,2-ethanedione, 1,2-bis(4-methylphenyl)- 3457-48-5 InChI=1/C16H14O2/c1-11-3-7-13(8-4-11)15(17)16(18)14-9-5-12(2)6-10-14/h3-10H,1-2H contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 250.38 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.
