(5-Chloro-2-methoxy-phenyl)-methanethiol CAS 1155100-13-2

Description

The occurrence of (5-Chloro-2-methoxy-phenyl)-methanethiol is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(5-Chloro-2-methoxy-phenyl)-methanethiol (CAS 1155100-13-2) is a high-purity analytical reference standard with the molecular formula C8H9ClOS and a molecular weight of 188.67 g/mol.

Structurally, (5-Chloro-2-methoxy-phenyl)-methanethiol (C8H9ClOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 188.67 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.

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.
