Chemical Structure
Description
The occurrence of Vinyl acetate-crotonic acid-vinyl neodecanoate terpolymer is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Vinyl acetate-crotonic acid-vinyl neodecanoate terpolymer (CAS 58748-38-2), molecular formula C12H22O2C4H6O2 and molecular weight 284.40 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Vinyl acetate-crotonic acid-vinyl neodecanoate terpolymer (C12H22O2C4H6O2) 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 284.40 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).
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), Vinyl acetate-crotonic acid-vinyl neodecanoate terpolymer 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.
