Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(4-Methylbenzoyl)-2H,4H,5H-benzo[g]indazole (CAS 339101-46-1) is a high-purity analytical reference standard with the molecular formula C19H16N2O and a molecular weight of 288.34 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 2-(4-Methylbenzoyl)-2H,4H,5H-benzo[g]indazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 288.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures 2-(4-Methylbenzoyl)-2H,4H,5H-benzo[g]indazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
