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-Hydrazinyl-6-methylpyrimidin-4-amine.
2-Hydrazinyl-6-methylpyrimidin-4-amine (CAS 33575-13-2), molecular formula C5H9N5 and molecular weight 139.16 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C5H9N5, 2-Hydrazinyl-6-methylpyrimidin-4-amine contains a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 139.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
