Chemical Structure

Ac-Leu-Val-Lys-aldehyde CAS 147600-40-6 chemical structure

Description

Ac-Leu-Val-Lys-aldehyde (C19H36N4O4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Ac-Leu-Val-Lys-aldehyde (CAS 147600-40-6), molecular formula C19H36N4O4 and molecular weight 384.51 g/mol, is a CATO reference standard with documented purity and traceability.

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 Ac-Leu-Val-Lys-aldehyde 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.
