The occurrence of Butanedioic acid, 2-methylene-, polymer with ethyl 2-propenoate, methyl 2-propenoate and 2-methyl-2-propenoic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Butanedioic acid, 2-methylene-, polymer with ethyl 2-propenoate, methyl 2-propenoate and 2-methyl-2-propenoic acid (CAS 67785-35-7), a certified reference material (molecular formula C5H6O4C5H8O2C4H6O2, MW 316.31 g/mol) for analytical method development and quality control.
Structurally, Butanedioic acid, 2-methylene-, polymer with ethyl 2-propenoate, methyl 2-propenoate and 2-methyl-2-propenoic acid (C5H6O4C5H8O2C4H6O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 316.31 g/mol, it falls into the moderately-high-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), Butanedioic acid, 2-methylene-, polymer with ethyl 2-propenoate, methyl 2-propenoate and 2-methyl-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.
