Description
As a certified reference material (CRM), (6R,7R)-7-amino-3-(imidazo[1,2-b]pyridazin-1(5H)-ylmethyl)-8-oxo-5-thia-1-azabicyclo[4.2.0]Oct-2-ene-2-carboxylic acid hydroiodide 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.
(6R,7R)-7-amino-3-(imidazo[1,2-b]pyridazin-1(5H)-ylmethyl)-8-oxo-5-thia-1-azabicyclo[4.2.0]Oct-2-ene-2-carboxylic acid hydroiodide (CAS 197897-11-3), molecular formula C14H15N5O3SHI and molecular weight 461.27 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, iodine substitution, (6R,7R)-7-amino-3-(imidazo[1,2-b]pyridazin-1(5H)-ylmethyl)-8-oxo-5-thia-1-azabicyclo[4.2.0]Oct-2-ene-2-carboxylic acid hydroiodide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 461.27 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.
