Chemical Structure

17B(H),21a(H)-Hopane CAS 1176-44-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 412.73 g/mol gives 17B(H),21a(H)-Hopane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

17B(H),21a(H)-Hopane (CAS 1176-44-9) is a high-purity analytical reference standard with the molecular formula C30H52 and a molecular weight of 412.73 g/mol.

Owing to an aromatic ring system, 17B(H),21a(H)-Hopane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 412.73 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), 17B(H),21a(H)-Hopane 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.
