4-Chloro-5H,6H,7H,8H-pyrido[4,3-d]pyrimidine hydrochloride CAS 1172808-59-1

Description

The occurrence of 4-Chloro-5H,6H,7H,8H-pyrido[4,3-d]pyrimidine hydrochloride is closely related to a nitrile group, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Chloro-5H,6H,7H,8H-pyrido[4,3-d]pyrimidine hydrochloride (CAS 1172808-59-1) is a high-purity analytical reference standard with the molecular formula C7H8ClN3HCl and a molecular weight of 206.07 g/mol.

The molecular framework of 4-Chloro-5H,6H,7H,8H-pyrido[4,3-d]pyrimidine hydrochloride (C7H8ClN3HCl) is characterized by a nitrile group, chlorine substitution, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), 4-Chloro-5H,6H,7H,8H-pyrido[4,3-d]pyrimidine hydrochloride 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.
