Chemical Structure
Description
Fmoc-Ala-Ala-Pro-OH (CAS 161220-53-7) is a high-purity analytical reference standard with the molecular formula C26H29N3O6 and a molecular weight of 479.52 g/mol.
Fmoc-Ala-Ala-Pro-OH (C26H29N3O6) 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. 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.
As a certified reference material (CRM), Fmoc-Ala-Ala-Pro-OH 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.
