Chemical Structure
Description
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.
CATO supplies 2-Butenedioic acid (2E)-, polymer with 1,4-cyclohexanedimethanol (CAS 66415-50-7), a certified reference material (molecular formula C8H16O2C4H4O4, MW 260.29 g/mol) for analytical method development and quality control.
Structurally, 2-Butenedioic acid (2E)-, polymer with 1,4-cyclohexanedimethanol (C8H16O2C4H4O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 260.29 g/mol, it falls into the medium-molecular-weight range. 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).
As a certified reference material (CRM), 2-Butenedioic acid (2E)-, polymer with 1,4-cyclohexanedimethanol 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.
