2-(4-Chloro-5-cyano-pyrrolo[2,3-d]pyrimidin-7-yl)acetic acid CAS 2122273-77-0

Description

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.

2-(4-Chloro-5-cyano-pyrrolo[2,3-d]pyrimidin-7-yl)acetic acid (CAS 2122273-77-0) is a high-purity analytical reference standard with the molecular formula C9H5ClN4O2 and a molecular weight of 236.61 g/mol.

The molecular framework of 2-(4-Chloro-5-cyano-pyrrolo[2,3-d]pyrimidin-7-yl)acetic acid (C9H5ClN4O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

As a certified reference material (CRM), 2-(4-Chloro-5-cyano-pyrrolo[2,3-d]pyrimidin-7-yl)acetic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
