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 {4,5-dimethyl-4H,7H-[1,2,3,4]tetrazolo[1,5-a]pyrimidin-6-yl}methanol.
{4,5-dimethyl-4H,7H-[1,2,3,4]tetrazolo[1,5-a]pyrimidin-6-yl}methanol (CAS 1803604-43-4) is a high-purity analytical reference standard with the molecular formula C7H11N5O and a molecular weight of 181.20 g/mol.
The molecular framework of {4,5-dimethyl-4H,7H-[1,2,3,4]tetrazolo[1,5-a]pyrimidin-6-yl}methanol (C7H11N5O) is characterized by an amide group, a hydroxyl group, an ether linkage, 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. 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.
