Description

The occurrence of (3alpha,5beta,9beta,10alpha)-pimara-8(14),15-diene-3,9-diol 150943-96-7 3alpha,9beta-dihydroxy-ent-sandaracopimaradiene CHEBI:78259 ent-sandaracopimaradien-3alpha,7beta-diol oryzalexin E is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(3alpha,5beta,9beta,10alpha)-pimara-8(14),15-diene-3,9-diol 150943-96-7 3alpha,9beta-dihydroxy-ent-sandaracopimaradiene CHEBI:78259 ent-sandaracopimaradien-3alpha,7beta-diol oryzalexin E (CAS 150943-96-7) is a high-purity analytical reference standard with the molecular formula C20H32O2 and a molecular weight of 304.47 g/mol.

The molecular framework of (3alpha,5beta,9beta,10alpha)-pimara-8(14),15-diene-3,9-diol 150943-96-7 3alpha,9beta-dihydroxy-ent-sandaracopimaradiene CHEBI:78259 ent-sandaracopimaradien-3alpha,7beta-diol oryzalexin E (C20H32O2) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), (3alpha,5beta,9beta,10alpha)-pimara-8(14),15-diene-3,9-diol 150943-96-7 3alpha,9beta-dihydroxy-ent-sandaracopimaradiene CHEBI:78259 ent-sandaracopimaradien-3alpha,7beta-diol oryzalexin E 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.
