Description
CATO supplies 5-[[9-[[(9H-Fluoren-9-ylmethoxy)carbonyl]amino]-9H-xanthen-3-yl]oxy]pentanoic Acid (CAS 168897-70-9), a certified reference material (molecular formula C33H29NO6, MW 535.59 g/mol) for analytical method development and quality control.
Structurally, 5-[[9-[[(9H-Fluoren-9-ylmethoxy)carbonyl]amino]-9H-xanthen-3-yl]oxy]pentanoic Acid (C33H29NO6) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 20.0, corresponding to approximately 20 ring(s) or double-bond equivalent(s). With a molecular weight of 535.59 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.
