Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 332.52 g/mol gives 3-Methyl-15-phenylpentadecanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Methyl-15-phenylpentadecanoic acid (CAS 116754-80-4) is a high-purity analytical reference standard with the molecular formula C22H36O2 and a molecular weight of 332.52 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, 3-Methyl-15-phenylpentadecanoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 332.52 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 3-Methyl-15-phenylpentadecanoic acid 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.
