Descrizione generale

Succinyl-β-cyclodextrin is a negatively charged cyclodextrin derivative that has major implications in the chiral separation of neutral and basic analytes by means of capillary electrophoresis (CE), owing to its counter-current mobility.[1][2][3]

Applicazioni

Cyclodextrins (CD) are cyclic oligosaccharides composed of D-glucose units connected via α(1→4) glycosidic bonds. Common cyclodextrins contain six (α-CD); seven (β-CD) or eight (gamma-CD) D-glucose units. Cyclodextrins are sometimes derivitized through esterification at positions two, three and/or six.
Succinyl-β-cyclodextrin and carboxymethyl-β-cyclodextrin are used as chiral selective agents in capillary electrophoresis for the separation of di- and tri-peptide enantiomers and catechin enantiomers. Succinyl-β-cyclodextrin is used to optimize analysis of PNA-DNA duplexes with diethylthiadicarbocyanine dye.
Succinyl-β-cyclodextrin may be used as a chiral selector to resolve:
  • Acylamine fungicides in commercial agrochemical formulations by electrokinetic chromatography (EKC).[4][5]
  • Catechin isomers[6] in human biological samples and antihistamines[2] in pharmaceutical preparations by CE.

Questions

  1. What is the molecular weight of this product?

    1 answer
    1. The molecular weight for the β-Cyclodextrin moiety is 1135 g/mole and the contribution from the succinic acid portion is 100.1 g/mole. This mass is used for succinic acid as water is lost during the condensation reaction when cyclodextrin and succinic acid form the conjugate. Thus, the average molecular formula and average formula weight can be expressed as the following. C42H70-nO35 • (C4H5O3)n or 1135.0 + n •100.1 The average degree of substitution for this product is ~3.5 for this product making the molecular weight approximately ~1485 g/mole for this product. The degree of substitution can vary from 2.5 - 5 for this product and the batch specific certificate of analysis should be reviewed to gather the degree of substitution (n).
