Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Guanosine 5-[γ-Thio]triphosphate Tetralithium Salt.
CATO supplies Guanosine 5-[γ-Thio]triphosphate Tetralithium Salt (CAS 94825-44-2), a certified reference material (molecular formula C10H12N5O13P3SLi, MW 542.15 g/mol) for analytical method development and quality control.
Guanosine 5-[γ-Thio]triphosphate Tetralithium Salt (C10H12N5O13P3SLi) contains a carbohydrate-derived structure, an amide group, a sulfone group, a phosphate ester group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
