Chemical Structure

Hematoxylin Hydrate CAS 517-28-2 chemical structure

Description

Hematoxylin Hydrate (CAS 517-28-2), molecular formula N/A and molecular weight N/A g/mol, is a CATO reference standard with documented purity and traceability.

Hematoxylin Hydrate 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.
