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 2,4-dichloro-5,7-dimethyl-7H-pyrrolo[2,3-d]pyrimidine.
CATO supplies 2,4-dichloro-5,7-dimethyl-7H-pyrrolo[2,3-d]pyrimidine (CAS 1638764-36-9), a certified reference material (molecular formula C8H15Cl2N3, MW 224.13 g/mol) for analytical method development and quality control.
The molecular framework of 2,4-dichloro-5,7-dimethyl-7H-pyrrolo[2,3-d]pyrimidine (C8H15Cl2N3) is characterized by a nitrile group, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
