Chemical Structure
Description
The occurrence of W4C9Z5BCV7 4238-71-5 1-Benzylimidazole 1-Benzyl-1H-imidazole Imidazole, 1-benzyl- (8CI) 1H-Imidazole, 1-(phenylmethyl)- AI3-52572 BI CCRIS 5821 EINECS 224-200-4 NSC 126828 NSC 217337 UNII-W4C9Z5BCV7 is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
W4C9Z5BCV7 4238-71-5 1-Benzylimidazole 1-Benzyl-1H-imidazole Imidazole, 1-benzyl- (8CI) 1H-Imidazole, 1-(phenylmethyl)- AI3-52572 BI CCRIS 5821 EINECS 224-200-4 NSC 126828 NSC 217337 UNII-W4C9Z5BCV7 (CAS 4238-71-5), molecular formula C10H20N2 and molecular weight 168.28 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, W4C9Z5BCV7 4238-71-5 1-Benzylimidazole 1-Benzyl-1H-imidazole Imidazole, 1-benzyl- (8CI) 1H-Imidazole, 1-(phenylmethyl)- AI3-52572 BI CCRIS 5821 EINECS 224-200-4 NSC 126828 NSC 217337 UNII-W4C9Z5BCV7 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 168.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
