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 Butanedioic acid, 2-methylene-, polymer with 1,3-butadiene, ethenylbenzene and 2-propenoic acid (CAS 26102-56-7), a certified reference material (molecular formula C5H6O4C8H8C3H4O2C4H6, MW 360.41 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, Butanedioic acid, 2-methylene-, polymer with 1,3-butadiene, ethenylbenzene and 2-propenoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 360.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Butanedioic acid, 2-methylene-, polymer with 1,3-butadiene, ethenylbenzene and 2-propenoic 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.
