Chemical Structure
Description
The occurrence of L-arabino-D-allo-Tridec-12-enose, 3,7:6,10-dianhydro-2,4,5,12,13-pentadeoxy-8,9,11-tris-O-[(1,1-dimethylethyl)dimethylsilyl]-13-iodo- is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
L-arabino-D-allo-Tridec-12-enose, 3,7:6,10-dianhydro-2,4,5,12,13-pentadeoxy-8,9,11-tris-O-[(1,1-dimethylethyl)dimethylsilyl]-13-iodo- (CAS 252905-91-2), molecular formula C31H61IO6Si3 and molecular weight 740.97 g/mol, is a CATO reference standard with documented purity and traceability.
L-arabino-D-allo-Tridec-12-enose, 3,7:6,10-dianhydro-2,4,5,12,13-pentadeoxy-8,9,11-tris-O-[(1,1-dimethylethyl)dimethylsilyl]-13-iodo- (C31H61IO6Si3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
