Chemical Structure
Description
D-Glycero-D-talo-heptitol (CAS 488-38-0) is a high-purity analytical reference standard with the molecular formula C7H16O7 and a molecular weight of 212.20 g/mol.
Structurally, D-Glycero-D-talo-heptitol (C7H16O7) contains a carbohydrate-derived structure. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 212.20 g/mol, it falls into the medium-molecular-weight range.
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.
