Chemical Structure
Description
The occurrence of L-Quebrachitol is closely related to a carbohydrate-derived structure in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
L-Quebrachitol (CAS 642-38-6), molecular formula C7H14O6 and molecular weight 194.18 g/mol, is a CATO reference standard with documented purity and traceability.
L-Quebrachitol (C7H14O6) contains a carbohydrate-derived structure. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
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), L-Quebrachitol 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.
