8-Methyl-5H-pyrimido[5,4-b]indol-4-ol CAS 296264-35-2

Description

CATO manufactures 8-Methyl-5H-pyrimido[5,4-b]indol-4-ol 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.

8-Methyl-5H-pyrimido[5,4-b]indol-4-ol (CAS 296264-35-2), molecular formula C11H9N3O and molecular weight 199.21 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 8-Methyl-5H-pyrimido[5,4-b]indol-4-ol is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 199.21 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
