Description
CATO supplies Cefazolin Sodium Salt (CAS 27164-46-1), a certified reference material (molecular formula C14H13N8O4S3Na, MW 476.48 g/mol) for analytical method development and quality control.
Structurally, Cefazolin Sodium Salt (C14H13N8O4S3Na) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.5, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 476.48 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
