Chemical Structure
Description
The occurrence of 4-Selenocyanatobut-1-ene is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Selenocyanatobut-1-ene (CAS 397843-18-4), molecular formula C5H7NSe and molecular weight 160.08 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Selenocyanatobut-1-ene (C5H7NSe) is characterized by a nitrile group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 4-Selenocyanatobut-1-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.
