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-Chloro-6,7-difluoroquinolin-3-yl)methanol (CAS 209909-03-5), molecular formula C7H10O3 and molecular weight 142.15 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (2-Chloro-6,7-difluoroquinolin-3-yl)methanol (C7H10O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 142.15 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), (2-Chloro-6,7-difluoroquinolin-3-yl)methanol 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.
