Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 183.21 g/mol gives Benzophenone-13C (carbonyl-13C) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Benzophenone-13C (carbonyl-13C) (CAS 32488-48-5), molecular formula C12[13C]H10O and molecular weight 183.21 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Benzophenone-13C (carbonyl-13C) (C12[13C]H10O) contains a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 183.21 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Benzophenone-13C (carbonyl-13C) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
