Description

CATO supplies (1'R,2S,4'E,6'E,8'R,12'Z,16A'R,20a'R,22'R,23a'S)-8'-((R)-1-hydroxyethyl)-12',19',23a'-trimethyl-1',10',11',18',20a',23a'-hexahydro-14'H,16'H,17'H,22'H-spiro[oxirane-2,23'-[1,22]methano[1,6,12]trioxacyclooctadecino[3,4-d]chromene]-3',14'(8'H)-dione (CAS 16891-85-3), a certified reference material (molecular formula C29H38O8, MW 514.61 g/mol) for analytical method development and quality control.

Based on its molecular formula C29H38O8, (1'R,2S,4'E,6'E,8'R,12'Z,16A'R,20a'R,22'R,23a'S)-8'-((R)-1-hydroxyethyl)-12',19',23a'-trimethyl-1',10',11',18',20a',23a'-hexahydro-14'H,16'H,17'H,22'H-spiro[oxirane-2,23'-[1,22]methano[1,6,12]trioxacyclooctadecino[3,4-d]chromene]-3',14'(8'H)-dione contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 514.61 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), (1'R,2S,4'E,6'E,8'R,12'Z,16A'R,20a'R,22'R,23a'S)-8'-((R)-1-hydroxyethyl)-12',19',23a'-trimethyl-1',10',11',18',20a',23a'-hexahydro-14'H,16'H,17'H,22'H-spiro[oxirane-2,23'-[1,22]methano[1,6,12]trioxacyclooctadecino[3,4-d]chromene]-3',14'(8'H)-dione 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.
