Chemical Structure

(E)-4-Chlorobut-2-en-1-ol CAS 1775-39-9 chemical structure

Description

As a certified reference material (CRM), (E)-4-Chlorobut-2-en-1-ol 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.

(E)-4-Chlorobut-2-en-1-ol (CAS 1775-39-9), molecular formula C4H7ClO and molecular weight 106.55 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (E)-4-Chlorobut-2-en-1-ol (C4H7ClO) is characterized by a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
