19806-17-8 ZQX9GRV3OO m-Phenylenediacetic acid Acetic acid, 2,2'-(m-phenylene)di- 1,3-Benzenediacetic acid (9CI) 3-09-00-04294 (Beilstein Handbook Reference) m-Benzenediacetic acid BRN 2616749 EINECS 243-332-3 NSC 75867 UNII-ZQX9GRV3OO (CAS 19806-17-8), molecular formula C10H16O4 and molecular weight 200.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 19806-17-8 ZQX9GRV3OO m-Phenylenediacetic acid Acetic acid, 2,2'-(m-phenylene)di- 1,3-Benzenediacetic acid (9CI) 3-09-00-04294 (Beilstein Handbook Reference) m-Benzenediacetic acid BRN 2616749 EINECS 243-332-3 NSC 75867 UNII-ZQX9GRV3OO (C10H16O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
