Chemical Structure
Description
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.
Chlorhexidine-d8 Dihydrochloride (CAS 1246816-96-5), molecular formula C22H22D8Cl2N10 and molecular weight 513.50 g/mol, is a CATO reference standard with documented purity and traceability.
Chlorhexidine-d8 Dihydrochloride (C22H22D8Cl2N10) contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
