Description
As a certified reference material (CRM), 1,3-Benzenedicarboxylic acid, polymer with 12-aminododecanoic acid and 1,4-butanediol 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.
1,3-Benzenedicarboxylic acid, polymer with 12-aminododecanoic acid and 1,4-butanediol (CAS 73003-20-0) is a high-purity analytical reference standard with the molecular formula C12H25NO2C8H6O4C4H10O2 and a molecular weight of 471.59 g/mol.
The molecular framework of 1,3-Benzenedicarboxylic acid, polymer with 12-aminododecanoic acid and 1,4-butanediol (C12H25NO2C8H6O4C4H10O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
