2-Hydroxypentanedioic Acid 1,2,3,4-13C4 Disodium Salt CAS 1429051-81-9

Description

The occurrence of 2-Hydroxypentanedioic Acid 1,2,3,4-13C4 Disodium Salt is closely related to a carboxylic acid group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2-Hydroxypentanedioic Acid 1,2,3,4-13C4 Disodium Salt (CAS 1429051-81-9), a certified reference material (molecular formula C[13C]4H6O5 2*Na, MW 133.06 g/mol) for analytical method development and quality control.

The molecular framework of 2-Hydroxypentanedioic Acid 1,2,3,4-13C4 Disodium Salt (C[13C]4H6O5 2*Na) is characterized by a carboxylic acid group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.
