Sodium rel-2,2'-(((1R,2R)-cyclohexane-1,2-diyl)bis((carboxymethyl)azanediyl))diacetate CAS 57137-35-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Sodium rel-2,2'-(((1R,2R)-cyclohexane-1,2-diyl)bis((carboxymethyl)azanediyl))diacetate.

Sodium rel-2,2'-(((1R,2R)-cyclohexane-1,2-diyl)bis((carboxymethyl)azanediyl))diacetate (CAS 57137-35-6), molecular formula C14H18N2O8NaH and molecular weight 366.30 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Sodium rel-2,2'-(((1R,2R)-cyclohexane-1,2-diyl)bis((carboxymethyl)azanediyl))diacetate (C14H18N2O8NaH) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.5, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 366.30 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
