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 Pyrimidin-5-ylzinc bromide, 0.50 M in THF.
Pyrimidin-5-ylzinc bromide, 0.50 M in THF (CAS 1227941-02-7), molecular formula BrZnC4H3N2 and molecular weight 224.37 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Pyrimidin-5-ylzinc bromide, 0.50 M in THF (BrZnC4H3N2) contains a salt form, a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 224.37 g/mol, it falls into the medium-molecular-weight range. 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.
