Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 178.60 g/mol gives Halquinol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Halquinol (CAS 8067-69-4), a certified reference material (molecular formula N/A, MW 178.60 g/mol) for analytical method development and quality control.
Halquinol is supplied as a fully characterized reference material; its structural identity, assigned purity, and stability data are documented in the batch-specific Certificate of Analysis (COA).
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.
