(Z)-1,3-Diiodo-2-butene CAS 134005-20-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (Z)-1,3-Diiodo-2-butene.

(Z)-1,3-Diiodo-2-butene (CAS 134005-20-2) is a high-purity analytical reference standard with the molecular formula C4H6I2 and a molecular weight of 307.90 g/mol.

Structurally, (Z)-1,3-Diiodo-2-butene (C4H6I2) contains iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 307.90 g/mol, it falls into the moderately-high-molecular-weight range. 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), (Z)-1,3-Diiodo-2-butene 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.
