Chemical Structure
Description
(1S,3S,4S)-3-hydroxy-7-azabicyclo[2.2.1]Heptane-1-carboxylic acid (CAS 186958-03-2), molecular formula C7H11NO3 and molecular weight 157.17 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (1S,3S,4S)-3-hydroxy-7-azabicyclo[2.2.1]Heptane-1-carboxylic acid (C7H11NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 157.17 g/mol, it falls into the medium-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.
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.
