Chemical Structure

H-DL-Lys(Ac)-OH CAS 1071-49-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including H-DL-Lys(Ac)-OH.

CATO supplies H-DL-Lys(Ac)-OH (CAS 1071-49-4), a certified reference material (molecular formula C8H16N2O3, MW 188.22 g/mol) for analytical method development and quality control.

The molecular framework of H-DL-Lys(Ac)-OH (C8H16N2O3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
