Description
As a certified reference material (CRM), BRL 37344 Sodium 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.
BRL 37344 Sodium (CAS 127299-93-8) is a high-purity analytical reference standard with the molecular formula C19H21ClNO4Na and a molecular weight of 385.82 g/mol.
Based on its molecular formula C19H21ClNO4Na, BRL 37344 Sodium contains a salt form, a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 385.82 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.
