Chemical Structure

Methyl (4aS,6aS,6bS,8aR,12aS,14aR,14bS,Z)-11-(hydroxymethylene)-2,2,6a,6b,9,9,12a-heptamethyl-10,14-dioxo-1,3,4,5,6,6a,6b,7,8,8a,9,10,11,12,12a,14,14a,14b-octadecahydropicene-4a(2H)-carboxylate CAS 305818-39-7 chemical structure

Description

The molecular framework of Methyl (4aS,6aS,6bS,8aR,12aS,14aR,14bS,Z)-11-(hydroxymethylene)-2,2,6a,6b,9,9,12a-heptamethyl-10,14-dioxo-1,3,4,5,6,6a,6b,7,8,8a,9,10,11,12,12a,14,14a,14b-octadecahydropicene-4a(2H)-carboxylate (C32H46O5) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Methyl (4aS,6aS,6bS,8aR,12aS,14aR,14bS,Z)-11-(hydroxymethylene)-2,2,6a,6b,9,9,12a-heptamethyl-10,14-dioxo-1,3,4,5,6,6a,6b,7,8,8a,9,10,11,12,12a,14,14a,14b-octadecahydropicene-4a(2H)-carboxylate (CAS 305818-39-7), molecular formula C32H46O5 and molecular weight 510.70 g/mol, is a CATO reference standard with documented purity and traceability.

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,6aS,6bS,8aR,12aS,14aR,14bS,Z)-11-(hydroxymethylene)-2,2,6a,6b,9,9,12a-heptamethyl-10,14-dioxo-1,3,4,5,6,6a,6b,7,8,8a,9,10,11,12,12a,14,14a,14b-octadecahydropicene-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.
