Chemical Structure
Description
Methyl 4-bromotetrahydro-2H-pyran-4-carboxylate (CAS 1192067-13-2) is a high-purity analytical reference standard with the molecular formula C7H11BrO3 and a molecular weight of 223.06 g/mol.
Methyl 4-bromotetrahydro-2H-pyran-4-carboxylate (C7H11BrO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
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.
