Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Methyl-1-{6-phenylthieno[2,3-d]pyrimidin-4-yl}-1h-pyrazol-5-amine.
3-Methyl-1-{6-phenylthieno[2,3-d]pyrimidin-4-yl}-1h-pyrazol-5-amine (CAS 379246-01-2), molecular formula C16H13N5S and molecular weight 307.37 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Methyl-1-{6-phenylthieno[2,3-d]pyrimidin-4-yl}-1h-pyrazol-5-amine (C16H13N5S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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.
