1,9-Nonanedicarboxylic Acid CAS 1852-04-6 chemical structure

Description

1,9-Nonanedicarboxylic Acid (CAS 1852-04-6) is a high-purity analytical reference standard with the molecular formula C11H20O4 and a molecular weight of 216.27 g/mol.

Structurally, 1,9-Nonanedicarboxylic Acid (C11H20O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 216.27 g/mol, it falls into the medium-molecular-weight range. 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.

As a certified reference material (CRM), 1,9-Nonanedicarboxylic Acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
