Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Benzene, ethenyl-, polymer with cyclopentene and 2-methyl-1,3-butadiene.
Benzene, ethenyl-, polymer with cyclopentene and 2-methyl-1,3-butadiene (CAS 98085-64-4), molecular formula C8H8C5H8 and molecular weight 172.27 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Benzene, ethenyl-, polymer with cyclopentene and 2-methyl-1,3-butadiene (C8H8C5H8) contains an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 172.27 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), Benzene, ethenyl-, polymer with cyclopentene and 2-methyl-1,3-butadiene 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.
