Chemical Structure
Description
As a certified reference material (CRM), 2-(3-Hydroxypropyl)pyridin-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.
2-(3-Hydroxypropyl)pyridin-3-ol (CAS 70381-91-8) is a high-purity analytical reference standard with the molecular formula C8H11NO2 and a molecular weight of 153.18 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 2-(3-Hydroxypropyl)pyridin-3-ol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 153.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
