Chemical Structure
Description
The occurrence of 5-Fluoro-2-(methoxy-d3)benzoic acid is closely related to deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Fluoro-2-(methoxy-d3)benzoic acid (CAS 2762044-24-4) is a high-purity analytical reference standard with the molecular formula C8H4D3FO3 and a molecular weight of 173.16 g/mol.
Structurally, 5-Fluoro-2-(methoxy-d3)benzoic acid (C8H4D3FO3) contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.5, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 173.16 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
