Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 166.60 g/mol gives 1-Chloro-3-(oxiran-2-ylmethoxy)propan-2-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Chloro-3-(oxiran-2-ylmethoxy)propan-2-ol (CAS 3944-63-6), molecular formula C6H11ClO3 and molecular weight 166.60 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Chloro-3-(oxiran-2-ylmethoxy)propan-2-ol (C6H11ClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 166.60 g/mol, it falls into the medium-molecular-weight range. 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.
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.
