Chemical Structure
Description
The occurrence of 5-(Chloromethyl)-3-(propan-2-yl)-4,5-dihydro-1,2-oxazole is closely related to an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-(Chloromethyl)-3-(propan-2-yl)-4,5-dihydro-1,2-oxazole (CAS 1311318-05-4) is a high-purity analytical reference standard with the molecular formula C7H12ClNO and a molecular weight of 161.63 g/mol.
5-(Chloromethyl)-3-(propan-2-yl)-4,5-dihydro-1,2-oxazole (C7H12ClNO) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
