Chemical Structure

5-(Chloromethyl)-3-methyl-4,5-dihydroisoxazole CAS 69578-12-7 chemical structure

Description

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.

5-(Chloromethyl)-3-methyl-4,5-dihydroisoxazole (CAS 69578-12-7) is a high-purity analytical reference standard with the molecular formula C5H8ClNO and a molecular weight of 133.58 g/mol.

5-(Chloromethyl)-3-methyl-4,5-dihydroisoxazole (C5H8ClNO) 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
