Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies GIE35Q69C1 116303-65-2 Sarafotoxin b Sarafotoxin S 6b (reduced) Sarafotoxin-b Sarafotoxin-b (Atractaspis engaddensis clone S33) UNII-GIE35Q69C1 (CAS 116303-65-2), a certified reference material (molecular formula C110H163N27O34S5, MW 2567.96 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, GIE35Q69C1 116303-65-2 Sarafotoxin b Sarafotoxin S 6b (reduced) Sarafotoxin-b Sarafotoxin-b (Atractaspis engaddensis clone S33) UNII-GIE35Q69C1 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 2567.96 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.

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.
