Chemical Structure
Description
17-(3-Hydroxypropyl-13C3)-6β,7β:15β,16β-dimethyleneandrostane-3β,5β,17β-triol (CAS 1264137-83-8) is a high-purity analytical reference standard with the molecular formula C21[13C]3H38O4 and a molecular weight of 393.53 g/mol.
The molecular framework of 17-(3-Hydroxypropyl-13C3)-6β,7β:15β,16β-dimethyleneandrostane-3β,5β,17β-triol (C21[13C]3H38O4) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
