Chemical Structure
Description
3-Cyclopropylthiophene-2-carbaldehyde (CAS 29481-31-0) is a high-purity analytical reference standard with the molecular formula C8H8OS and a molecular weight of 152.21 g/mol.
The molecular framework of 3-Cyclopropylthiophene-2-carbaldehyde (C8H8OS) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
