Chemical Structure
Description
The occurrence of L-Glutamic Acid Hydrochloride (100 mg) is closely related to a carbohydrate-derived structure, an amide group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
L-Glutamic Acid Hydrochloride (100 mg) (CAS 138-15-8) is a high-purity analytical reference standard with the molecular formula C5H9NO4HCl and a molecular weight of 183.59 g/mol.
Based on its molecular formula C5H9NO4HCl, L-Glutamic Acid Hydrochloride (100 mg) contains a carbohydrate-derived structure, an amide group, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 183.59 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), L-Glutamic Acid Hydrochloride (100 mg) 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.
