Chemical Structure

5-Chloro-2H-chromen-2-one CAS 38169-98-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Chloro-2H-chromen-2-one.

5-Chloro-2H-chromen-2-one (CAS 38169-98-1), molecular formula C6H10O4C6H14O3C5H12O2 and molecular weight 384.47 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5-Chloro-2H-chromen-2-one (C6H10O4C6H14O3C5H12O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 384.47 g/mol, it falls into the moderately-high-molecular-weight range.

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.
