Description

508WVS56PW 2973-76-4 5-Bromovanillin Benzaldehyde, 3-bromo-4-hydroxy-5-methoxy- EINECS 221-016-6 NSC 10073 NSC 29037 Vanillin, 5-bromo- UNII-508WVS56PW (CAS 2973-76-4), molecular formula C8H13BrO3 and molecular weight 237.09 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C8H13BrO3, 508WVS56PW 2973-76-4 5-Bromovanillin Benzaldehyde, 3-bromo-4-hydroxy-5-methoxy- EINECS 221-016-6 NSC 10073 NSC 29037 Vanillin, 5-bromo- UNII-508WVS56PW contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 237.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
