Chemical Structure

K-F-H-E-K-H-H-S-H-R-G-Y CAS 127637-03-0 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies K-F-H-E-K-H-H-S-H-R-G-Y (CAS 127637-03-0), a certified reference material (molecular formula C70H99N25O17, MW 1561.80 g/mol) for analytical method development and quality control.

Structurally, K-F-H-E-K-H-H-S-H-R-G-Y (C70H99N25O17) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 34.0, corresponding to approximately 34 ring(s) or double-bond equivalent(s). With a molecular weight of 1561.80 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
