1-(3-Thienyl)-2-propyn-1-ol CAS 153026-78-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(3-Thienyl)-2-propyn-1-ol.

1-(3-Thienyl)-2-propyn-1-ol (CAS 153026-78-9), molecular formula C7H6OS and molecular weight 138.19 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-(3-Thienyl)-2-propyn-1-ol (C7H6OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
