Chemical Structure
Description
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.
trans-2-[2-(3-Bromophenyl)-2-oxoethyl]cyclohexane-1-carboxylic acid (CAS 735274-85-8), molecular formula C15H17BrO3 and molecular weight 325.20 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, trans-2-[2-(3-Bromophenyl)-2-oxoethyl]cyclohexane-1-carboxylic acid (C15H17BrO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 325.20 g/mol, it falls into the moderately-high-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.
