Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 623564-40-9 R56JYB8P8Z BLI-489 UNII-R56JYB8P8Z 4-Thia-1-azabicyclo(3.2.0)hept-2-ene-2-carboxylic acid, 6-((5,6-dihydro-8H-imidazo(2,1-c)(1,4)oxazin-2-yl)methylene)-7-oxo-, sodium salt (1:1), (5R,6Z)- BLI 489.

623564-40-9 R56JYB8P8Z BLI-489 UNII-R56JYB8P8Z 4-Thia-1-azabicyclo(3.2.0)hept-2-ene-2-carboxylic acid, 6-((5,6-dihydro-8H-imidazo(2,1-c)(1,4)oxazin-2-yl)methylene)-7-oxo-, sodium salt (1:1), (5R,6Z)- BLI 489 (CAS 623564-40-9), molecular formula C13H14N3O4SNaH2O and molecular weight 349.34 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, 623564-40-9 R56JYB8P8Z BLI-489 UNII-R56JYB8P8Z 4-Thia-1-azabicyclo(3.2.0)hept-2-ene-2-carboxylic acid, 6-((5,6-dihydro-8H-imidazo(2,1-c)(1,4)oxazin-2-yl)methylene)-7-oxo-, sodium salt (1:1), (5R,6Z)- BLI 489 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 349.34 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.

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.
