Chemical Structure

17a(H),21B(H)-30-Norhopane CAS 53584-60-4 chemical structure

Description

The occurrence of 17a(H),21B(H)-30-Norhopane is closely related to an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

17a(H),21B(H)-30-Norhopane (CAS 53584-60-4) is a high-purity analytical reference standard with the molecular formula C29H50 and a molecular weight of 398.71 g/mol.

Owing to an aromatic ring system, 17a(H),21B(H)-30-Norhopane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 398.71 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.

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), 17a(H),21B(H)-30-Norhopane 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.
