Description
As a certified reference material (CRM), Acetyl Tetrapeptide-11 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies Acetyl Tetrapeptide-11 (CAS 928006-88-6), a certified reference material (molecular formula C27H38N4O7, MW 530.61 g/mol) for analytical method development and quality control.
Based on its molecular formula C27H38N4O7, Acetyl Tetrapeptide-11 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 530.61 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
