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 ((2'-(5H-tetrazol-5-yl)-[1,1'-biphenyl]-4-yl)methyl)valine.
((2'-(5H-tetrazol-5-yl)-[1,1'-biphenyl]-4-yl)methyl)valine (CAS CATO-C3D-262892), molecular formula C19H21N5O2 and molecular weight 351.40 g/mol, is a CATO reference standard with documented purity and traceability.
((2'-(5H-tetrazol-5-yl)-[1,1'-biphenyl]-4-yl)methyl)valine (C19H21N5O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. 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.
