This product is commonly referred to as Graham′s salt. The literature suggests that typically the n is 6, to make it sodium hexametaphosphate. However, this is not included in the product testing nor has this been verified. The end user would have to verify this empirically.

Application
- Novel method for the preparation of controlled-release theophylline granules coated with a polyelectrolyte complex of sodium polyphosphate-chitosan.: This paper presents a novel approach to creating controlled-release theophylline granules using a coating made from a polyelectrolyte complex of sodium polyphosphate and chitosan. This method could significantly impact pharmaceutical formulations by improving drug release profiles and patient compliance (Kawashima et al., 1985).

Is it polydisperse or mono disperse?
1 answer-
This product is Graham's salt, in which typically n=6, to make it sodium hexametaphosphate, and in the form of a cyclic hexamer. This should make it a relatively monodisperse product. However, this is not included in the testing specifications, so it cannot be confirmed. This would need to be verified empirically.
