Chemical Structure

4-Chloropent-4-en-1-ol CAS 1647-18-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 120.58 g/mol gives 4-Chloropent-4-en-1-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Chloropent-4-en-1-ol (CAS 1647-18-3) is a high-purity analytical reference standard with the molecular formula C5H9ClO and a molecular weight of 120.58 g/mol.

4-Chloropent-4-en-1-ol (C5H9ClO) contains a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
