Chemical Structure
Description
3-Butyl-3-(chloromethyl)tetrahydro-2h-pyran (CAS 1695954-62-1) is a high-purity analytical reference standard with the molecular formula C10H19ClO and a molecular weight of 190.71 g/mol.
Structurally, 3-Butyl-3-(chloromethyl)tetrahydro-2h-pyran (C10H19ClO) contains 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 190.71 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.
