Chemical Structure
Description
The occurrence of 5,6-Dimethylpyridin-3-ol is closely related to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5,6-Dimethylpyridin-3-ol (CAS 61893-00-3), molecular formula C7H9NO and molecular weight 123.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system, 5,6-Dimethylpyridin-3-ol is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 123.15 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.
As a certified reference material (CRM), 5,6-Dimethylpyridin-3-ol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
