Chemical Structure
Description
The occurrence of (5-chlorothiophen-2-yl)methanol is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(5-chlorothiophen-2-yl)methanol (CAS 74168-69-7) is a high-purity analytical reference standard with the molecular formula C5H9ClOS and a molecular weight of 152.64 g/mol.
Structurally, (5-chlorothiophen-2-yl)methanol (C5H9ClOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, 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 152.64 g/mol, it falls into the medium-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.
