Chemical Structure
Description
2-(aziridin-1-yl)-3-(2-chloroethyl)-1,3,2-oxazaphosphinane 2-oxide (CAS 29102-47-4), molecular formula C7H14ClN2O2P and molecular weight 224.63 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-(aziridin-1-yl)-3-(2-chloroethyl)-1,3,2-oxazaphosphinane 2-oxide (C7H14ClN2O2P) contains an amide group, organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.5, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 224.63 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.
