Chemical Structure

919769-83-8 Cyclopenta[c]pyran-3(1H)-one, hexahydro-4a,5,7-trihydroxy-7-methyl-,(4aS,5R,7S,7aR)- CAS 919769-83-8 chemical structure

Description

The occurrence of 919769-83-8 Cyclopenta[c]pyran-3(1H)-one, hexahydro-4a,5,7-trihydroxy-7-methyl-,(4aS,5R,7S,7aR)- is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 919769-83-8 Cyclopenta[c]pyran-3(1H)-one, hexahydro-4a,5,7-trihydroxy-7-methyl-,(4aS,5R,7S,7aR)- (CAS 919769-83-8), a certified reference material (molecular formula C9H14O5, MW 202.20 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 919769-83-8 Cyclopenta[c]pyran-3(1H)-one, hexahydro-4a,5,7-trihydroxy-7-methyl-,(4aS,5R,7S,7aR)- is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 202.20 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).
