2-[(1R)-1-[(2-{bis[(tert-butoxy)carbonyl]amino}-5-bromopyridin-3-yl)oxy]ethyl]-4-fluorobenzoic acid CAS 1643141-17-6 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-[(1R)-1-[(2-{bis[(tert-butoxy)carbonyl]amino}-5-bromopyridin-3-yl)oxy]ethyl]-4-fluorobenzoic acid.

CATO supplies 2-[(1R)-1-[(2-{bis[(tert-butoxy)carbonyl]amino}-5-bromopyridin-3-yl)oxy]ethyl]-4-fluorobenzoic acid (CAS 1643141-17-6), a certified reference material (molecular formula C24H40BrFN2O7, MW 567.49 g/mol) for analytical method development and quality control.

Structurally, 2-[(1R)-1-[(2-{bis[(tert-butoxy)carbonyl]amino}-5-bromopyridin-3-yl)oxy]ethyl]-4-fluorobenzoic acid (C24H40BrFN2O7) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 567.49 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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

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.
