Chemical Structure
Description
The occurrence of 1-Chloro-3-ethylpent-2-ene is closely related to chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-Chloro-3-ethylpent-2-ene (CAS 761-20-6), a certified reference material (molecular formula C7H13Cl, MW 132.63 g/mol) for analytical method development and quality control.
Structurally, 1-Chloro-3-ethylpent-2-ene (C7H13Cl) contains chlorine 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 132.63 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 1-Chloro-3-ethylpent-2-ene 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.
