Chemical Structure

2-Butenedioic acid (2Z)-, 1,4-dibutyl ester, polymer with ethenyl acetate and 2-propenoic acid CAS 29861-55-0 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Butenedioic acid (2Z)-, 1,4-dibutyl ester, polymer with ethenyl acetate and 2-propenoic acid.

2-Butenedioic acid (2Z)-, 1,4-dibutyl ester, polymer with ethenyl acetate and 2-propenoic acid (CAS 29861-55-0), molecular formula C12H20O4C4H6O2C3H4O2 and molecular weight 386.44 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-Butenedioic acid (2Z)-, 1,4-dibutyl ester, polymer with ethenyl acetate and 2-propenoic acid (C12H20O4C4H6O2C3H4O2) 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 386.44 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 2-Butenedioic acid (2Z)-, 1,4-dibutyl ester, polymer with ethenyl acetate 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.
