Chemical Structure

(S)-2-Chloropentanedioic acid CAS 1369533-83-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 166.56 g/mol gives (S)-2-Chloropentanedioic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (S)-2-Chloropentanedioic acid (CAS 1369533-83-4), a certified reference material (molecular formula C5H7ClO4, MW 166.56 g/mol) for analytical method development and quality control.

Structurally, (S)-2-Chloropentanedioic acid (C5H7ClO4) contains a carbohydrate-derived structure, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 166.56 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
