BL4O920FS6 168434-89-7 Coniochaetone B UNII-BL4O920FS6 Cyclopenta(b)(1)benzopyran-9(1H)-one, 2,3-dihydro-1,8-dihydroxy-6-methyl-, (1R)- Cyclopenta(b)(1)benzopyran-9(1H)-one, 2,3-dihydro-1,8-dihydroxy-6-methyl-, (R)- (CAS 168434-89-7), molecular formula C13H12O4 and molecular weight 232.23 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, BL4O920FS6 168434-89-7 Coniochaetone B UNII-BL4O920FS6 Cyclopenta(b)(1)benzopyran-9(1H)-one, 2,3-dihydro-1,8-dihydroxy-6-methyl-, (1R)- Cyclopenta(b)(1)benzopyran-9(1H)-one, 2,3-dihydro-1,8-dihydroxy-6-methyl-, (R)- is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 232.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
