6-chloro-8-prop-1-ynyl-2H-chromene-3-carboxylic acid CAS 2625769-31-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-chloro-8-prop-1-ynyl-2H-chromene-3-carboxylic acid.

6-chloro-8-prop-1-ynyl-2H-chromene-3-carboxylic acid (CAS 2625769-31-3), molecular formula C13H15ClO3 and molecular weight 254.71 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 6-chloro-8-prop-1-ynyl-2H-chromene-3-carboxylic acid (C13H15ClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 254.71 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
