Chemical Structure
Description
CATO supplies 17a(H),21B(H)-(22R)-Homohopane (CAS 60305-22-8), a certified reference material (molecular formula C31H54, MW 426.76 g/mol) for analytical method development and quality control.
Owing to an aromatic ring system, 17a(H),21B(H)-(22R)-Homohopane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 426.76 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 17a(H),21B(H)-(22R)-Homohopane 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.
