Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Naphtho[1,2-b]thiophen-2-ylmethanol.
Naphtho[1,2-b]thiophen-2-ylmethanol (CAS 35813-68-4) is a high-purity analytical reference standard with the molecular formula C13H10OS and a molecular weight of 214.28 g/mol.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, Naphtho[1,2-b]thiophen-2-ylmethanol is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 214.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
