Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 316.78 g/mol gives H-Orn(Z)-OMe · HCl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
H-Orn(Z)-OMe · HCl (CAS 5874-75-9) is a high-purity analytical reference standard with the molecular formula C14H20N2O4HCl and a molecular weight of 316.78 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, H-Orn(Z)-OMe · HCl is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 316.78 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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-Orn(Z)-OMe · 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.
