Chemical Structure
Description
(2-Methylbenzo[b]thiophen-7-yl)methanol (CAS 1234844-99-5), molecular formula C10H10OS and molecular weight 178.25 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (2-Methylbenzo[b]thiophen-7-yl)methanol (C10H10OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 178.25 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
