Chemical Structure
Description
H-Lys-Ser-OH · HCl (CAS 275366-32-0), molecular formula C9H19N3O4HCl and molecular weight 269.73 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, H-Lys-Ser-OH · HCl is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 269.73 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), H-Lys-Ser-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.
