Chemical Structure

H-Ser(Ac)-OH · HCl CAS 66638-22-0 chemical structure

Description

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.

H-Ser(Ac)-OH · HCl (CAS 66638-22-0) is a high-purity analytical reference standard with the molecular formula C5H9NO4HCl and a molecular weight of 183.59 g/mol.

H-Ser(Ac)-OH · HCl (C5H9NO4HCl) contains a carbohydrate-derived structure, an amide group, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.

As a certified reference material (CRM), H-Ser(Ac)-OH · HCl 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.
