Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Chloro-5,6,7,8-tetrahydropyrido[3,4-d]pyrimidine hydrochloride.
2-Chloro-5,6,7,8-tetrahydropyrido[3,4-d]pyrimidine hydrochloride (CAS 1432795-17-9) is a high-purity analytical reference standard with the molecular formula C7H8ClN3HCl and a molecular weight of 206.07 g/mol.
2-Chloro-5,6,7,8-tetrahydropyrido[3,4-d]pyrimidine hydrochloride (C7H8ClN3HCl) contains a nitrile group, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 2-Chloro-5,6,7,8-tetrahydropyrido[3,4-d]pyrimidine hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
