Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 316.43 g/mol gives Cinerin I distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Cinerin I (CAS 25402-06-6), molecular formula C20H28O3 and molecular weight 316.43 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C20H28O3, Cinerin I contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 316.43 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Cinerin I 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.
