Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 6-amino-5-cyano-2-[({3-cyano-5H,6H,7H,8H,9H-cyclohepta[b]pyridin-2-yl}sulfanyl)methyl]-4-(pyridin-3-yl)-4H-pyran-3-carboxylate.
Ethyl 6-amino-5-cyano-2-[({3-cyano-5H,6H,7H,8H,9H-cyclohepta[b]pyridin-2-yl}sulfanyl)methyl]-4-(pyridin-3-yl)-4H-pyran-3-carboxylate (CAS 625375-71-5) is a high-purity analytical reference standard with the molecular formula C26H25N5O3S and a molecular weight of 487.57 g/mol.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Ethyl 6-amino-5-cyano-2-[({3-cyano-5H,6H,7H,8H,9H-cyclohepta[b]pyridin-2-yl}sulfanyl)methyl]-4-(pyridin-3-yl)-4H-pyran-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 487.57 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.
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.
