Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 370.65 g/mol gives 17B(H)-22,29,30-Trisnorhopane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 17B(H)-22,29,30-Trisnorhopane (CAS 51271-94-4), a certified reference material (molecular formula C27H46, MW 370.65 g/mol) for analytical method development and quality control.
The molecular framework of 17B(H)-22,29,30-Trisnorhopane (C27H46) is characterized by an aromatic ring system. 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 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.
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.
