Methyl 12-oxo-12-phenyldodecanoate CAS 104828-35-5 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Methyl 12-oxo-12-phenyldodecanoate (CAS 104828-35-5) is a high-purity analytical reference standard with the molecular formula C19H28O3 and a molecular weight of 304.42 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, Methyl 12-oxo-12-phenyldodecanoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), Methyl 12-oxo-12-phenyldodecanoate 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.
