Chemical Structure

Palmitoyl-L-Glutamic Acid CAS 38079-66-2 chemical structure

Description

Palmitoyl-L-Glutamic Acid (CAS 38079-66-2), molecular formula C21H39NO5 and molecular weight 385.54 g/mol, is a CATO reference standard with documented purity and traceability.

Palmitoyl-L-Glutamic Acid (C21H39NO5) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 Palmitoyl-L-Glutamic Acid 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.
