Chemical Structure
Description
The occurrence of 3-Chloropropiophenone(2-d2) is closely related to deuterium isotope labeling, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Chloropropiophenone(2-d2) (CAS 34236-34-5), molecular formula C9H7D2ClO and molecular weight 170.63 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 3-Chloropropiophenone(2-d2) is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 170.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
