Obeticholic Acid Intermediate Supplier: The Rol...
One molecule, three names, two routes. Why 7-ketolithocholic acid is both UDCA impurity F and the scaffold on which obeticholic acid is built.

Chenodeoxycholic Acid Specification: A Quick-Re...
One page of the CDCA monograph that matters: every parameter, its limit, and the four figures that differ from UDCA — the ones most often carried across by mistake.

UDCA Particle Size Distribution (D90) and Table...
Particle size is the one UDCA parameter the pharmacopoeia does not define — which is why it is so often quoted loosely. What D10, D50 and D90 mean, and what...

Residual Solvents in UDCA: An ICH Q3C Guide for...
UDCA specifications are silent on residual solvents because a separate guideline governs them. This guide maps the ICH Q3C classes, the limits that apply, and what a solvent list reveals...

Lithocholic Acid: UDCA EP Impurity C Limit and ...
Of the nine lettered EP impurities of UDCA, only one gets a dedicated test. This is lithocholic acid, impurity C — identity, the 0.1% limit, the TLC method, and what...
