Chemical Structure

(E)-5-chloropenta-1,3-diene CAS 40596-30-3 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 (E)-5-chloropenta-1,3-diene.

(E)-5-chloropenta-1,3-diene (CAS 40596-30-3), molecular formula C5H7Cl and molecular weight 102.56 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (E)-5-chloropenta-1,3-diene (C5H7Cl) contains chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 102.56 g/mol, it falls into the low-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.

CATO manufactures (E)-5-chloropenta-1,3-diene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
