Chemical Structure
Description
4-Bromotetrahydro-2H-pyran-4-carboxylic acid (CAS 1803600-06-7), molecular formula C6H9BrO3 and molecular weight 209.04 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Bromotetrahydro-2H-pyran-4-carboxylic acid (C6H9BrO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
