Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 9,12-Octadecadienoic acid (9Z,12Z)-, polymer with 2-(chloromethyl)oxirane, ethenylbenzene, 4,4'-(1-methylethylidene)bis[phenol] and 2-methyl-2-propenoic acid.

9,12-Octadecadienoic acid (9Z,12Z)-, polymer with 2-(chloromethyl)oxirane, ethenylbenzene, 4,4'-(1-methylethylidene)bis[phenol] and 2-methyl-2-propenoic acid (CAS 68928-91-6) is a high-purity analytical reference standard with the molecular formula C18H32O2C15H16O2C8H8C3H5ClOC4H6O2 and a molecular weight of 791.51 g/mol.

Based on its molecular formula C18H32O2C15H16O2C8H8C3H5ClOC4H6O2, 9,12-Octadecadienoic acid (9Z,12Z)-, polymer with 2-(chloromethyl)oxirane, ethenylbenzene, 4,4'-(1-methylethylidene)bis[phenol] and 2-methyl-2-propenoic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 791.51 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 9,12-Octadecadienoic acid (9Z,12Z)-, polymer with 2-(chloromethyl)oxirane, ethenylbenzene, 4,4'-(1-methylethylidene)bis[phenol] 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.
