Methyl (4aS,6aR,6bR,8aR,10S,12aR,12bR,14aR,14bS)-10-acetoxy-2,2,6a,6b,9,9,12a-heptamethyl-14-oxoicosahydropicene-4a(2H)-carboxylate CAS 25493-94-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl (4aS,6aR,6bR,8aR,10S,12aR,12bR,14aR,14bS)-10-acetoxy-2,2,6a,6b,9,9,12a-heptamethyl-14-oxoicosahydropicene-4a(2H)-carboxylate.

CATO supplies Methyl (4aS,6aR,6bR,8aR,10S,12aR,12bR,14aR,14bS)-10-acetoxy-2,2,6a,6b,9,9,12a-heptamethyl-14-oxoicosahydropicene-4a(2H)-carboxylate (CAS 25493-94-1), a certified reference material (molecular formula C33H52O5, MW 528.76 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Methyl (4aS,6aR,6bR,8aR,10S,12aR,12bR,14aR,14bS)-10-acetoxy-2,2,6a,6b,9,9,12a-heptamethyl-14-oxoicosahydropicene-4a(2H)-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 528.76 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), Methyl (4aS,6aR,6bR,8aR,10S,12aR,12bR,14aR,14bS)-10-acetoxy-2,2,6a,6b,9,9,12a-heptamethyl-14-oxoicosahydropicene-4a(2H)-carboxylate 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.
