Nα-p-Tosyl-L-lysine methyl ester hydrochloride CAS 5266-48-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Nα-p-Tosyl-L-lysine methyl ester hydrochloride.

CATO supplies Nα-p-Tosyl-L-lysine methyl ester hydrochloride (CAS 5266-48-8), a certified reference material (molecular formula C14H22N2O4SHCl, MW 350.86 g/mol) for analytical method development and quality control.

The molecular framework of Nα-p-Tosyl-L-lysine methyl ester hydrochloride (C14H22N2O4SHCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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. 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.

CATO manufactures Nα-p-Tosyl-L-lysine methyl ester hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
