Description
As a certified reference material (CRM), Silvex 2-ethylhexyl ester 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.
Silvex 2-ethylhexyl ester (CAS 53404-76-5), molecular formula C17H23Cl3O3 and molecular weight 381.72 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Silvex 2-ethylhexyl ester (C17H23Cl3O3) contains a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 381.72 g/mol, it falls into the moderately-high-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.
