Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 172.61 g/mol gives 2-Chloropropiophenone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Chloropropiophenone (CAS 6084-17-9), molecular formula C8H9ClO2 and molecular weight 172.61 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Chloropropiophenone (C8H9ClO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
