Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 190.16 g/mol gives Bromocycloheptane-d distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Bromocycloheptane-d (CAS 35558-50-0), molecular formula C7D13Br and molecular weight 190.16 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Bromocycloheptane-d (C7D13Br) contains deuterium isotope labeling, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.5, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 190.16 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
