2,9-Didecylnaphtho[2,3-b]naphtho[2',3':4,5]thieno[2,3-d]thiophene CAS 1169932-40-4 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

2,9-Didecylnaphtho[2,3-b]naphtho[2',3':4,5]thieno[2,3-d]thiophene (CAS 1169932-40-4) is a high-purity analytical reference standard with the molecular formula C42H52S2 and a molecular weight of 620.99 g/mol.

Based on its molecular formula C42H52S2, 2,9-Didecylnaphtho[2,3-b]naphtho[2',3':4,5]thieno[2,3-d]thiophene contains sulfur-containing functionality, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 620.99 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
